Hi all,
The wavecom modem is a class B device, which means:
"Can be connected to GPRS service and GSM service (voice, SMS), but
using only one or the other at a given time. During GSM service (voice
call or SMS), GPRS service is suspended, and then resumed automatically
after the GSM service (voice call or SMS) has concluded. Most GPRS
mobile devices are Class B."
But from a programming point of view, there is only one device:
/dev/ttyS2. I'm using wvdial for GPRS. Once GPRS is connected, opening
/dev/ttyS2 would fail. I can of course kill wvdial each time I need to
send SMS but 1. it's ugly, 2. it sounds like for class B device this is
not necessary.
Anybody how this works?
Thanks
