BATTERY POVVERED DEVICE
BACKGROUND TO THE INVENTION
The present invention relates to a battery powered electronic device and
particularly, but not exclusively, to battery-powered cellular telephones, and methods
S of operating cellular telephones and cellular telephnn.o networks.
In ~l~$igning consumer electronics products - such as cellular telephones,
other cl mmlmi~tions or data processing equipment or audio-visual equipment suchas camcorders - there is a general need to provide hllpl~v~d performance and
additional operational features so as to çnh~nre the attractiveness of the product to
10 the consumer. On the other hand, for each such product there is usually a sector of
the market which is extremely price sel~iLiY~. For this part of the market there is
a need to skip out all but the most essential features in order to ~..i,.;.,.i~ the price.
These conflicting needs can be met by providing dirr~l~nL design~s for the different
market sectors, but then there is a loss of the economies of scale which might
15 otherwise be obtained.
Another important design factor in the m~mlf~ lre of battery-powered
products is the need to m~ximi.ce battery life. Particularly in relation to cellular
telephones, the m~ximnm standby time, that is the time for which the telephone can
be left not in active collullul~ication but in re~lin~ocs to receive a call, is an important
20 performance parameter. It is, for example, one of the most frequently quoted
parameters in culll~laLi~e reviews of such phones. Despite the practical and
commercial importance of this parameter, it has not hitherto proved possible to
extend the standby time for a typical ETACS phone much beyond 24 hours using a
600 mAHr battery.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention, there is provided a
battery-powered portable electronic device including an interchangeable battery pack
~ fitted to a main unit of the device, characterised by an auxiliary functional unit
SUBSTITUTE SHEET (RULE 26)
CA 02226~13 1998-01-07
WO 97/03534 PCT/S~f 5.'~-C0
contained within the battery pack and arranged to cs~.. -ie;"~ data bidirectionally
with circuits within the main unit of the device, the auxiliary functional unit thereby
~elrollmllg t_e auxiliary function in collju~lcLio~ with the said circuits within the
main unit of the device.
S By an auxiliary function is meant a function which adds to or enh~nres the
imal~y functioning of the device and not merely charge management or other
functions of the type convellLionally associated with battery packs.
This aspect of the present invention takes advantage of the fact that the
battery-powered electronic device ..~ocçss~. ;Iy has at least one hl~ ;hallgeable module
10 and associated interf~re~ namely that of the battery pack itself. By providing
auxiliary functional units which fit within the battery pack, and using the Pnh~nrec~
battery pack interf~re, the invention makes it possible for the same basic unit to
provide dirrc:lcllL levels of function for dirr~;lcllL sectors of the market, while
m~i..l;.i..i.~, m~Yimllm ecc)nnmi~-s of scale. All this is achieved without adding
15 sif~nifie~ntly to the size, complexity or cost of the base-level model, since no
additional intPrf~re is required.
In the case of a cellular telephone, the auxiliary functional unit might
colll~lise, for çY~mrle, an ~ls~ g m~rhin~, a silent vih.~lli..g alarm, a cordless
phone or a pager as ~ cn~e(l below in relation to the other aspects of the invention.
20 The unit may provide two or more such functions in combination, for example both
an al~w~lillg m~rhine and a pager.
Preferably the main unit of the device inrllltles a user input device and is
arranged to c.~.. -ir~le control signals to the auxiliary functional unit in response
to a user input. The user input device might be, for eY~mrle, the keypad of a
25 cellular telephone and may be used to program and control the auxiliary fimrtion~l
unit via the battery pack interface.
Preferably the int~orf~ee for the battery pack inrlllr~es a connection for the
tr~n~mi~sion of power from the main unit to the auxiliary functional unit.
Although the auxiliary unit is located adjacent the battery power supply, it is
30 found to be advantag~eous for many purposes if it is not directly connected to the
b~tteries, but l~ceiv~s its power via the main unit. This reduces the need for power
switching or control ch~;uik y within the auxiliary unit.
CA 02226~13 1998-01-07
WO 97/03534 PCTISG96/00006
This aspect of the invention also ~c~ ses a battery pack incorporating
an auxiliary filnrtion~l unit.
According to a second aspect of the present invention, there is provided a
cellular tPlP.phonP, ch~r~ctPri~Pcl by a pager module povv~.~d independently of the
5 p~ aly telephony circuits of the telephone and arranged to power-up the said
telephony circuits when a paging signal is received.
This aspect of the invention takes a novel approach to the problem of
extending the standby time of a cellular telephnnP. Instead of ~LL~ Lil~g to enh~nre
the batteries or to reduce the power drain of the telephony circuits, the present
10 illV~lLol~ have added to the tPlPphonP a pager module able to "wake-up" the phone
on receipt of a pager signal. This allows the main circuits to be turned OFF and so
reduces the battery drain from the 20 to 40 mA convention~lly associated with
standby mode to a much lower level, typically around 0.1 - 0.4 mA, associated with
the drain current of the pager in standby. By using the pager to provide the standby
15 fimr.ti~m, the ~.lv~ have been able to extend the standby lifetime of the phone
from around 24 hours to as long as 3 weeks, thereby doing away with the need for daily lcchdl~g of the baLLt;lies.
Preferably the pager module is arranged to cl)............ ;r~t~ caller line
i~ienti~lr~ti~n (CLI) data to the pl~l~y telephony circuits.
Preferably the pl.lllaly telephony circuits are arranged to display to the user
the CLI data received from the pager module.
Preferably the ~lillldly telephony circuits are arranged to make a registration
with the cellular network ~ltr,m~tir~lly after p.,welillg-up in response to a paging
slgnal.
It is found to be particularly advantageous to have the pager use CLI data to
ready the telephone to make a return call to the caller at the press of a button, should
the user wish to do so.
The pager is preferably fitted within a battery pack, in accordance with the
first aspect of the invention. In this case, preferably the pager is arranged toc"""".~,ir~te data bidirection~lly with the plilllaly telephony circuits via theconnPction between the battery pack and the main unit of the telephone.
CA 02226~il3 1998-01-07
WO 97/03534 PCTISG3. rl~
The phone may be arranged so that the user can choose bc;Lwe~ll one mode
in which, after the completion of the call, the plillldly telephony circuits are powered
down again, or a second and all~ iv~ mode, in which at the completion of the call
the telephony circuits remain ~ .,d, giving the user the option of making a further
5 call.
According to a third aspect of the present invention, there is provided a
method of operating a cellular telephone inrln-ling placing the telephone in a standby
mode to reduce power col~ulll~Lion, chz.r~c.teri~.-rl in that in standby mode power to
the ~lilllaly telephony circuits is turned OFF and power to a pager module remains
10 ON, and in that the pager module, on sl~bseq~lent1y l~ceivhlg a pager signal, ~wiL~ es
ON power to the lJlilllaly telephony circuits.
Optionally, at the end of the cullv~l~aLion upon detection of mobile/network
release, cellular phone IJl~aly circuit power may be switched OFF, and power to
the pager lclllail~s ON, ready for the next hlcollliug call.
Accolding to a fourth aspect of the present invention, there is provided a
method of up~laLillg a cellular telec~,.. l.,-ir;.lions network characterised by
Ll,...~..lil~;l-g a pager signal from the ll~Lwulh to a cellular telephone, receiving the
pager signal in a pager module in the cellular telephone while the lJlilllaly telephony
circuits of the cellular telephone are powered-down, switching ON power to the
20 ~lilllaly telephony circuits in response to the pager signal, and subsequently
establishing a cf~nnrcti-~n between the said ~lilllaly telephony circuits and the
network.
Preferably the method further culll~lises lc:ceivillg at the ll~;Lwolh exrh~nge
a ~estin~tion telephone number from a call originator, and
only when the ~ stin~tion cellular telephone is ~1~Le.. . . i . .--~ to be not
registered, then uuL~uLLillg from the ncLwolh exrh, nge a pager signal, and otherwise
establishing a connection directly with the L~ llaly telephony circuits of the
~lestin,~tif~n cellular telephone.
Preferably the llc~Lwolh exrh~nge stores a record of ~estin~tion numbers and
30 corresponding pager numbers, and when the ~lestin~tion cellular telephone is
llrtPrTninr(l to be not registered then retrieves the corresponding pager number for
use in .~ign, lling the pager module.

The present invention's approach to ~x~ cellphnn.- standby time can be
implemt--ntr~l simply using existing tel.ophnn~ and pager nc~Lwc,lh~. This however
requires the caller to have both the telephone ~ bel and pager number of the
de,stin~tion. This can be avoided, and the invention implemrntr-l in a manner
S ll~l~pal~llL to the user, if the lldwclh exrh~nge logs when a given phone is not
registered, and then retrieves and uses the corresponding pager number from a
~h~e to ~ it on the pager n~Lw~lh thereby ~wil~;hillg ON the phone and
enabling a connection to be made.

DESCRIPTION OF EXAMPLES
A battery-powered portable electronic device, in the present example a hand-
held cellular telephone or "h~nrlphone" 1 inrhl~1es an i..L~lchallg~able battery pack
30 2, which is fitted to the main body of the h~nflphonP 1 and is el~ctrir~lly connrctrd
to the h~n~lph( ne 1 via an i..l~ . ri-re 3. The handphone 1 includes a power
management circuit 4, a control microprocessor 5 and telephony tr~n~mi~ion/
CA 02226513 1998-01-07
WO 97/03534 PCT/S~ ~_6
reception circuits 6. A key pad 7 acts as a user input device, serving both the
dialling of numbers, and also for pro~,.. ~.. i~g of the diL~cuL functions of the
h~nrirhc)ne 1. The number dialled, and other inllir~tion~ relating to the functioning
of the phone are displayed on an LCD 8. These ~ uy circuits within the
S h~n~1rhnnl- 1 are all conventional in construction, and so will not be described in
further detail here.
Figures 2A and 2B show the exfrrn~l features of the h~nrlrhone 1 and battery
pack with AFU 2. As is collv~ on~l with h~n-lphone battery packs, the battery
pack when fitted to the phone is n~ rrn~lly held rigidly to the body of the device with
10 a connection established to the circuits of the handphone 1 using a pin and contact
arrangement. However, the pack may be released when, for example, it is decided
to recharge the bdU~lies.
In the present example the h~nt1rhnn-? uses a Lld~lliL frequency band from
872 MHz to 905 MHz and a receive frequency band from 917 MHz to 950 MHz.
15 It ~eldl~s in power class 4 with duplex spacing of 45 MHz and channel spacing of
25 KHz. The phone can access 1320 cll~nn~ It ct-l..,."..~ir~tPs using FM
mod~ ti~ n with FSK M~.~.'h~ jk;. coding. In this example, the phone has physical
Aimen~ion~ of 149 x 55 x 26.5 mm. It inrhl-1~s a 2 x 12 dot-matrix :~u~ Lwi~L LCD
with back lighting.
For conventional operation, in which the battery packs serves only to provide
power to the h~nrlrhnne 1, then the pack may contain collv~uLional AA (NiCd)
batteries. ~l~r.~ 1ivt:1y, as in the eY~mrl~ illn~tr~te~l, pi;~ ,.lir. NiMH or NiCd
batteries may be used. In this case, the battery pack holds in addition to the batteries
an auxiliary filnrtion~l unit (AFU) 10.
The batteries 9 supply power to the h~n-lphnne 1 via the int~ re 3. The
AFU 10 leceiv~s power from the h~ hn~r- 1 via the interf~ce and cu~ r~te~s
data bidirection~lly with the h~nrlphnnr 1 via the i"l~ . r~e It may be programmed
and controlled via the keypad 7 and l~ v~ ces~or 5 in the h~n~lrhnne 1. In a first
example illustrated in further detail in Figures 3 and SA to SC, the AFU is a pager.
As will be described in further detail below, this functions in combination with the
circuits in the handphone 1 to extend greatly the standby time of the handphone.

As seen in Figure 3, the cas~:w~,lh for the battery pack 2 is divided at
a~plo~ Lely half its height by an internal wall 31. A PCB 32 mounted on one sideof the dividing wall 31 provides the circuits of the pager. Four pri~m~tir b~tteries
33a to d are cont~inr~ in the pack below the dividing wall 31 and are electrically
5 cnnnect~d to the pack output pins 34 via contact pads 35. The pack includes a
l11F~ O1 36 (SEMITEC 103 AT-2) and a poly-switch 37 (RAYCHEM SRP200).
These both serve as safety devices to protect against O~ hF-~I;IIg of the pack when
charging. A ferrite ~nt.-nn~ 38 mounted directly on the PCB picks up the paging
signal Ll,...~i...illrd by the paging l~lwolk to the pager.
The output pins from the pack 34 are shown in further detail in Figure 3. It
co~ ,lise~ 10 pin contacts having a pitch of 2.54 mm. The battery ground and
battery positive contacts are located at the extreme ends. This is found to give better
electrir~ lÇulllla~ce. The pin labelled Pwr-to-Acc provides a power input signalto the accessory pack. The AFU electronics Ill~,.crole only get the power when the
15 pack is mounted on the main ele-;L~ ics. This Lll~lcfol~ provides an interlock
m~ch~ni~m for the pu~ il g-up of the AFU. Select line 1 and 2 are logic inputs
to the main electronics in-lir~tin~ the type of AFU being operated. The Ll~llliL data
and receive data pins cu------,-";~ signals carrying proprietary protocol i.lç~llnalion
between the main electronics and the AFU electronics and provide data tr~n~rti~n~
20 in respect of the pager, al~ hlg ...~rhi,.~ or other AFU.
The interf~re b~Lw~:ell the battery pack inrln-1ing the AFU and the main
electronics, i.e. the main circuits of the h~n~lphone in the present example, uses a
proprietary serial protocol de~ign~d to provide m~ximllm flexibility and ease ofco..."""-ir~lion It has two basic data formats. One to carry messages from main
electronics to e.~h~-r~-.Pnt (i.e. AFU) ele~ ics, the other in the reverse direction.
The protocol defines mFc~ge type fields, device i~l~ntifir~ti~n code fields, andlongit~ in~l reclnn~l~nr-y check (LRC) fields, in addition to data fields. It provides
a mech~ni~m for acknowledgement of data tr~n~rti~ns between the main electronicsand the enh~nee-m~nt (AFU) ele-;Llvllics.
In a second example shown in Figure 4, the AFU 10 contained within the
battery pack 2 is an al~vv.,lhlg m~rhin.-. As in the previous example, the electronics
CA 02226513 1998-01-07
WO 97/03534 PCT/S~
for the a~ ,.hlg m~rhinr are provided as a PCB 42 mounted on a dividing wall 41
of the battery pack, as shown in Figure 4.
A variety of other options are possible for the AFU. For example, it may
c~ ,- ;x~ a silent vibrating alarm to be used when desired in place of the usual audio
5 ringing tone of the h~n~lphon~ 1. The operation of the a-~wcli. g m~rhint- is
described in further detail below.
CORDLESS PHONE
A further option is that the AFU may enable the h~n(1rhnne to function as a
10 cordless phone. In this case the AFU col.L~..ls circuits for providing a relatively low
power radio frequency linh between the phone and a cordless phone base unit
cnnnrctr-l to a telephone line. The AFU the allows the AF circuits of the h~nflphnnr
to be used in making a convention~l telephone call via the t~l~,phnn~, line. While in
use in this manner the h~nrlrhnn~ is not in ~ ib~.ed with the cellular network and
15 does not incur charges from that llcLwulh.
ANSWERING MACHINE
The a~wcling m~rhin~ is tlescrihe~l in detail in Annex B. It inrlndPs a Solid
State memory for lccol~ g m~c~ges and includes an option for recording an
20 ongoing Cull~ ion between the h~ .hnlle user and a called or calling party.
SERIAL BUS PROTOCOL
The serial bus provides means to establish point-to-point c~,. ~ -- - -- - ,~ir~tinn between the
~n-lset and the Auxiliary Functional Unit (AFU). There are three types of

Either device i.e. the T~nrl~et or AFU may issue and respond to a set of comm~n~30 All messages are binary based (with the exception of monitor status where its data
is ASCII-based for ease of Lllo~ g). All messages are single word.

EXTENDING STANDBY TIME
The use of a pager in combination with a h~n-lphonP to extend the standby
time of the h~n~lrho~ will now be d~scrihe~l in further detail. The pager is
preferably, but not nPcPs~rily, provided as an AFU within a battery pack, as
~1PS~ rihed above.
Four modes of operation may be defined for a cellular phone:
20 (A) Full-OFF, battery not ~tt~r.h~-1 In this state t_ere is zero current drain from
the battery. The phone cannot originate a call, and cannot (~ lr. a call.
(B) Battery ~tt~.ht-rl, "Pagullar" standby. In this state there is a small current
drain and current going to the pager. The phone is in OFF state. Only the
wake-up circuits in the phone are powered to detect ON/OFF key press, or
wake-up signals from the pager module.
(C) Switched on, cu--v~ 1 standby mode. Here the cellular phone is not in
an act of co-~vc;~ ion with the base station but is "registered" and ready to
receive a call from the cellular base station. The battery drain is .cignific~nt in the range 20 - 50 mA.
30 (D) Switched on, call in l?rOgl~ss mode. Here the cellular phone is in activecu~ ion with a cellular base station. The battery drain in this mode
is very high, typically 500 to 700 mA.
CA 02226~13 1998-01-07
WO 97/03534 PCT/S~ 5.'.
11
Modes A, C and D are conventinn~l. Mode B is provided by phones
embodying the present invention, and provides an z~llr.~ 1iVC standby mode, termed
by the illV~llL~ "Pagullar standby" which enables a greatly hl~ ,a~ed standby time.
The battery standby time is the time ~lnr~tion in which the cellular phone can be in
S standby mode with a fully charged battery of pre-defined capacity measured in
mAHr. As already ~ ed, typically for ETACS type h~nt1rhones~ a standby time
of about 24 hours is achievable. In this example of the present invention, the
standby time is greatly ext.on~led through the use of a pager incorporated in the
handphone. The pager is conn~ctecl to the circuits of the h~n-lphone by an int~rf~re
10 of the type ~1est~rihe-1 above and is independently powered from the batteries via the
handphone. When in "Pagullar standby" mode the main circuits of the handphone
are switched off. The pager h~w~v~l rt;lllai~ in a standby state in which it has a
small current drain of around 0.1 - 0.4 mA. When a call is to be made to the
switched-off h~n-lphone, then a paging signal is sent to the pager which in turn15 Ll~nsllliL~ a control signal via the inttorf~ee to the h~nr1rhone to turn the handphone
ON. Two scP-n~rios for making or If III;II-I;IIg a call will now be described by way
of example.
Scen~rio A: This is a simple solution which can be implementr~l imm.~ tely
using e~ ting L~C~LWUll~ and without reqlliring co-operation belw~ the pager and20 mobile phone n~lwolh~. Following this scenario, the call originator uses the pager
ulllbel to make a page to the pager options pack in~lic~ting that he wants to make
contact with the cellular phone. On receipt of a paging signal, the caller's number
is captured by the pager using caller line i~le-ntifir~tion CLI. The pager then
Lldl~llliL~ a control signal to wake-up the phone and C~ "~ ir~tPS the CLI
~5 hlrolllldLion to the cellular phone via the i~ . rhre. The caller's number is displayed
on the h~n-1rhnnr display autom~tir~lly. Simn1t~nrously, the h~n-lphnne makes
registration with the cellular ll~twolh. Should the handphone user choose to return
the call, then he or she presses the SEND key, the cellular phone dials the CLI
number, and hence is able to return the calling party's telephone call. This approach
30 has the advantage of not reqlliring any modification to exi~ting network. However
it does require the caller to know both the telephone number and the pager number
CA 022265l3 l998-0l-07
WO 97/03534 PCT/SG96/00006
12
of the ~1e,ctin~tion. On return of the call, the cellular phone is the inhi~tor of the call
and hence has to pay that portion of the cost for the call.
Scenario B: This uses a modified mode of operation for the ~ wolh~ to
mahe the process more friendly to the user. It is however more complex to
S implement. It requires the co-u~ela~ll of the cellular and pager ~LWCJ1h operators
to include intelligçn~ e in the ll~Lw~lh m~n~gem.ont sor~w~. Following this
scenario, the call ~ri~in~tor mahes a call to the cellular phone number. The cellular
phone ll~Lwolh hnows that the phone is switched off and hence not l~ t~,r~d. Thecellular ll~;Lwolh then looks up in a d~t~h~e the equivalent pager number m~t~h~10 to the cellular phone number. Tldl~al~llLly to the calling party, the cellular phone
network i..il;n~s a paging call through the paging lwLwolh to wake-up the cellular
phone, awaits registration, and completes the call when the freshly awoken cellular
phone is l~ L~ d with the Il~Lwolh.
In this way, the caller does not need to hnow if the cellular phone is ~wiL~l~d
15 on, or if it has a pager option. The caller makes a "normal" call and the method of
operation is ~ lL both to the caller and the called party. The cellular phone
and the pager n~W~1h do the ~ign~llin~ O~ 11Y. While the operation of the
phone appears COll~t;. .1 ion~l to the user, the ability to switch off the main circuits and
leave just the pager in standby reduces a greatly increased standby time which may
20 be as long as 3 weeks.

1. Introduct;Qn
This document attempts to describe the objective features and ergonomics of the optional plug_in
pager for the 2nd Generation AMPS/TACS handphone from the end user point o~view.
It is envisioned that the pager will be housed in the battery compartment. Other than
incorporating the control into the keypad and display panel of the handphon~, no extra switch
and display will be provided by the plug-in pager. This document includes descriptions on the

3. M~n-M~chine Interf~cç
Since the plug-in pager is sharing the display (LCD panel and the top LED) and the keypad with
the handphone, the ergonomics of the pager are designed to be as consistent as possible to that of
the handphone.
Many of the icons and but'ons are shared between the handl~none and the pager. However, there
are certain buttons and icons dedicated for the plug-in pager only:
Icon Button
ACC MAIL BOX (~31)
~READ
The Mail Box Mode (thru' which the user may access paging messages) will be cancelled when
there is an incoming phone call. To make incoming call to have highest priority is consistent to
the basic ergonomics of the handphone.

1. Introduction
This document attempts to describe the objective feab~res and ergonomics of the optional plug-in
answering machine for the 2nd Generation AMPS/TACS handphone from the end user point of
ulew.
It is envisioned that the solid-state plug-ir answering machine will be house~ in the ban-ry
compartment: Other than incorporating the control into the keypad and display panel of the
handphone, no extra switch and display will be provided by the plug-in device. This document
includes descriptions on the host handphone ~CD display, usage of the keys, user selectable
options and mode of operations. However, it will not cover user requirements on mechanical and
perfo~nance parameters (such as audio levels, battery life etc.).
Listed below is the summary of the features:
O Menu-Driven Power On/Off
O 90 Seconds Playback/Record Capacity
O Personalized Outgoing Message (OGM~ Recording (15 seconds max)
O Factory Pre-recorded OGM (non-recoverable)
O Security Code for Personalized OGM Recording
O OGM Playback
O Incoming Message (~CI~) Recording for S Messages (each 15 seconds max)
O Automatic Disable When Memory Full
O Unread Message Indication
0 Allow User To Pick-Up Call While Recording ICM
O CLI-Tagged Recorded Voice Message Allows One-Touch Callback
(Only for TACS systems supporting CLI functions)

STX - Start of Transmission (0x02).
TYPE - Message type ~leld.
L)IC - Device Identification Code as defmed in Section 2.
DATA - (See description of individual messages).
ETX - End of Transmission (0-x03).
LRC - Longitudinal Redundancy Checl;. LRC is computed by XOR all the
characters from TYPE field up to ETX character inclusively. See the
following paragraphs: Sentinel(s) is not included in the calculation.
Original special characters (not - quoted" characters) are used in the
calculation.
Flow Control: ACK (0x06) / NACK (0x l S) protocol:
SENDER.
- Should not continue to send additional message word until the its last cent message
has been acknowledged ~ie ACK received). TIMEOUT= I second
- Sender should retry UP TO 3 T~MES when there is no response (ACK or NACK) or
NACK'd. The time interval between retries should be I to 2 second .
RECEIVER:
- Message word with r.un-zero calaculated LRC should be NACK'd; otherwise, the
incoming message should be ACK'd ASAP.
I'rovisious ~or Full Duple:c Operation:
- Special Characters:
STX - 0x02
ETX - 0x03
SENT~NEL - 0x88
ACK - 0x06
NACK - 0:;15

- In full duplex operation, it is possible that any of the above special characters may be
embedded into an on-going incoming message word (as well as the LRC). These
flow control characters is meant for a previously sent message in the opposite
direction.
r - When a party needs to respond with a ACK or NACK while it is also sending its own
message, it should send ACK or NACK immediately (the ACK/NACK character
shall not affect the LRC calculation of the message b_ing sent). The other partyshould recognize 0x06 or 0x l 5 as flow control characters (not part of the message).
- A SENTINEL (0x88) is defined to notice the receiving party that the byte that
follows immediately has been be "quoted" (XOR with 0xl 1) before sending out. For
example,
Original ~,Vord:
I

- The transmitted LRC field is calculated with the "pre-quoted" character (i.e. 0x06 in

"recovered" character.
