RE: Better modem than Wavecom

I did encounter the anoying behaviour where Kannel does not finish the
initialization of the modem, as the AT2 thread get stuck (freezes). I've
isolated that to the tcdrain() command in at2_write_line(). I noticed it
happens most times on the first AT command issued to the modem, and
rarely on the AT+CSMS command.
Did anyone seen this behaviour in wavecom or other modems ?
