[hylafax-users] note on new firmware of topic chipset (+FTS)

[Giulio Orsero <giulioo@pobox.com>]

This is just as a note for the archives.

We use topic chipset modems (don't ask why).

ati3
TP560 Data/Fax/Voice 56K Modem

They didn't support AT+FTS (using FTS would cause an ERROR during fax
sending causing failure)
===
ati1
External Controller Ver1.20, CheckSum=2FF2
OK
ati4
DSP Ver1.10 CheckSum=7A64
OK
ati7
Controller Ver1.20 Date:Feb 17 18:35
OK
at+fclass=1
OK
at+fts=?
ERROR
at+fts=7
ERROR         <==================
===

so that the HylaFAX modem prototype correctly avoids using +FTS


A new batch of modems arrived with a new firmware:
===
ati1
External Controller Ver3.00, CheckSum=14CC
ati4
DSP Ver3.00 CheckSum=B46B
ati7
Controller Ver3.00 Date:Aug 27 19:02 2001
OK
at+fclass=1
OK
at+fts=?
ERROR
at+fts=7
OK                   <=============== Note this
===

But note this also (this was due to a misconfigured system where a config
file was used that was not meant for topic, so that +FTS got used):
===
May 20 15:28:51.39: [ 7863]: --> [2:OK]
May 20 15:28:51.39: [ 7863]: <-- [9:AT+FTS=7\r]
May 20 15:28:51.41: [ 7863]: --> [2:OK]  <=== OK, but 70 ms have not elapsed
...
May 20 15:32:30.26: [ 7863]: SEND end page
May 20 15:32:33.87: [ 7863]: --> [2:OK]
May 20 15:32:33.87: [ 7863]: <-- [9:AT+FTS=9\r]
May 20 15:32:33.89: [ 7863]: --> [2:OK]  <=== OK, but 90 ms have not elapsed
May 20 15:32:33.89: [ 7863]: SEND send EOP (no more pages or documents)
May 20 15:32:33.89: [ 7863]: <-- [9:AT+FTH=3\r]
May 20 15:32:33.94: [ 7863]: --> [7:CONNECT]
===

So, modem prototype is still correct because, even if +FTS gives OK, it
seems it does not really work (it just says OK), but it may be confusing.
