<b>TI-89 Link Protocol Guide</b> - System Backup Transfers
<center>
<h2>
<hr align="center">Flash Transfers</h2>
</center>
<p><br>
<b><i>Beware:</i></b> in the worst case, a FLASH operation can
completely
lock up your calculator and there is no way than returning the
calcultator
to Texas Instruments in this case.
<br>
We (Tim. Singer and Romain Li&eacute;vin) can not be responsible of
this.
<br>
Personnaly, I (Romain) have crashed a FLASH OS several times without
crashing the calculator but you have been warned ! <br>
A last remark: the link cables which are the more reliable and
efficient for these operations (especially OS flashing) are RS232
cables such as Grey TIGL, fastAVRlink (even at 4x = 38400 bauds) or
PIClink (not tested but should work). The SilverLink is slower than
others for FLASHing (strange, don't ask us why !).
</p>
<p>There are 2 kinds of FLASH transfers:
<br>
- FLASH applications which are variables stored in the FLASH memory of
the calculator. <br>
- AMS (Advanced Mathematic Software) which is the Operating System
of the calculator.
<br>
A Flash transfer is a one (large) transmission containing data (up
to 2 Mb for AMS). The file format that the TI-89 Graph Link software
uses
can be found in the <a href="fformat.html#backup">file formats</a>
section
of this documentation.
</p>
<p>A FLASH OS must be transferred silently whereas FLASH apps can be
transferred manually or silently. Silent transfers can only be done
between a computer and a calculator, and require that the computer make
the <a href="#request">request</a> or <a href="#rts">request-to-send</a>.
</p>
<p>This section does not cover sending of certificates or applications
sold by TI.
</p>
<h4><a name="request"></a>Checking FLASH</h4>
The protocol for checking whether the calculator AMS has been upgraded
is described below.

<h4><a name="rts"></a>Requesting ID list</h4>
Indeed, the request is as if the TI requested the 'IDLIST' variable:
Ty=22
and Nl=00.
<br>
This request works only with upgraded calculator (check if TI has been
upgraded before).
<p>The protocol for silently receiving the ID list is shown below:

<h4><a name="rts"></a>Sending FLASH</h4>
<u><b><i>Warning:</i></b> We (Tim. Singer and Romain Li&eacute;vin)
could
not be responsible if your calculator has been locked or damaged with a

<br>
If a FLASH OS has been sent and the operation has crashed, you can
wait that the TI89 display 'Ready to receive'. Then, try again the
transfer.
<br>
If the calculator is really locked, remove batteries, wait some time
and put them again. Next, press I for 'Install code' and retry transfer.<br>

AMS releases sent 'basecode' but I'm unsure.<br>
TI89 Titanium and V200PLT use a slightly different packet :
<span style="font-weight: bold;">08 c9 09 0</span>0 b3 4e 14 00&nbsp;
23&nbsp; 00 08 00 0X&nbsp; <span style="font-weight: bold;">49 01</span>
where 0X is the hardware ID (1 = 92+, 3 = 89, 8
= V200, 9 = Titanium).
