I can reliably resolve this issue on a bv3 device with:

root at fic-gta01:~$ echo 1 > /sys/devices/platform/gta01-pm-gsm.0/power_on
root at fic-gta01:~$ cu -l /dev/ttySAC0
And then on a different console issue:
root at fic-gta01:~$ stty -F /dev/ttySAC0 crtscts

The order is important for me because cu seems to disable hardware flow control.
Also gsmd never had problems for me, so everyone who suspects hardware problems
might want to try
root at fic-gta01:~$ gsmd -F -s 115200 -p /dev/ttySAC0
and see if that returns any OK messages for the AT commands issued
