AW: AT driver patch

In the same vain: Using a SIM from Mexico, a recent Kannel snapshot failed
to send a SMS using a strange GSM mobile phone (CompactFlash format using a
CF-to-PCCard adapter). Investigating the problem revealed that Kannel did
not wait long enough for the ">" prompt to appear after the "AT+CMGS"
command.
Currently the timeout is set to 5 seconds. Increasing it to 15 seconds
solved the problem.

Betreff: AT driver patch


Hi folks.

A user reported to me having problems while initializing the modem 
after a while.
The log shows it gets no "OK" after AT&F. I however realized that it 
might simply not wait long enough. AT&F resets the modem and this might 
take a while on some old slow phones. Our default timeout of 3 seconds 
might simply be too slow for those.

I wrote the attached patch to work around this issue and also to retry 
the first few commands if it failed. This should make initialization 
more robust. Before I commit it to CVS I however want to have it tested 
by a couple of modem users with different types of modems to be sure it 
doesn't screw up something else.
