The AT stuff is really problematic. Look at the hoops ISDN and software
modem drivers go through to emulate AT commands. I know even of a
CDC-ACM modem which can't deal with AT commands inline (that's within
spec). It seems to me we should have a modem API in kernel.

For devices which don't deal in AT commands probably but for devices
whose firmware provides an AT command interface over serial I would
disagree.

I fully agree here. Even if you think you get AT commands under control,
you really won't in the end. That standard is so wildly mis-interpreted
that it is not even funny anymore.

Possibly. Does anyone known of any "species" bypassing AT commands entirely, 
other than Phonet? as far as GPRS is concerned?
