smsd and Sagem RT30

[Alastair Watts]

Hi guys,

I have a Sagem RT30 GSM device which talks AT commands to itself to read
status information from the GSM module.

The result is that this causes smsd to lose communication with the unit,
as smsd thinks that its commands are not getting through.

Is it possible to flush the serial input before sending each command
from smsd? Or parse all the input before throwing an error?

Gnokii version is 0.6.26, built from FreeBSD ports

Debug output from smsd (showing the conversation the unit has with
itself in the middle before the "lowlevel.c:461 error: 1, Command
failed." messages start):
