Hmmm, what is /etc/answer?  Mgetty doesn't use this (vgetty might, but
you're not using that).  So I'd consider this "random failure, random
luck".

The dealer has no idea what he's talking about.  This is very explicit
from the log file:

... the modem has "identified" the call as 19200 bps (?? must be the
serial port speed) and No Error Control - most likely, the 300bps fax
negotiation carrier, or something like this. Stoopid thing.

Second try:

> 08/10 15:53:00 yS1   mdm_command: string 'AT+FAA=1;+FCR=1'

the modem is initialized as before - adaptive answer (fax and data) = on.

... and this time it works.  Stoopid indeed.

If the modem doesn't understand this command, it can't do polling
(server-side), at least not in class 2 mode.  Period, no discussion.

... same for this: AT+FCIG is a prerequisite for polling (client) in class
2 mode, if that doesn't work, polling won't work.


As for a good recommendation: hard to say, I haven't any yet.
