Hi,
can somebody please explain me the differents of these
- echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
- s3c24xx-gpio b7=0
- echo "AT at POFF" >/dev/ttySAC0
When i look at the schematic then the MODEM_ON from calypso is on
GPB7 from s3c2442 and 's3c24xx-gpio b7=0' should Power Off the
calypso, right?
So what does echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
and echo "AT at POFF" >/dev/ttySAC0 do?
When I want to disable the GSM-Modem completely is then
echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on enough?
greets
Michael
