Comment(by arhuaco):
I'll start testing this bug.
# cd /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gsm.
# echo 0 > power_on; sleep 3; echo 1 > power_on; echo 1 > reset
# socat - file:/dev/ttySAC0,crtscts,crnl,b115200
ATZ
(No reply, strace shows: select(16, [0 3], [], [], NULL).
It's the first time I talk to the modem in the GTA02. I should have
received a reply from the modem, right?
BTW, I didn't get any reply with b8b36e5ec3db71d5. Do I need to enable
echo?
