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.

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.
