I tried to run cu several times after issuing stty -F /dev/ttySAC0 crtscts, and
now I get garbled output from the modem. After several lines it still hangs.
Examples:
root at fic-gta01:~$ echo 1 > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on
root at fic-gta01:~$ cu -l /dev/ttySAC0
Connected.
d Interpreter re
root at fic-gta01:~$ echo 1 > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on
root at fic-gta01:~$ cu -l /dev/ttySAC0
Connected.
OK

root at fic-gta01:~$ echo 1 > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on
root at fic-gta01:~$ cu -l /dev/ttySAC0

I also tried picocom, which didn't react after "Terminal ready", until I pressed
a key:

root at fic-gta01:~$ picocom -b 115200 -f h -p o -d 8 -i -r -l /dev/ttySAC0
