the UMTS PC-Cards you can get rather cheap these days show up as usb
controllers with usb-cereal converters behind. add a little kermit
magic and you're done (this is on OpenBSD).
unlock at boottime (replace 0000 with your PIN):
#!/usr/local/bin/kermit +
set line /dev/ttyU0
if failure exit 1
set carrier-watch off
set input echo on
lineout "AT+CPIN?"
input 10 "+CPIN: SIM PIN"
if failure exit 1
input 10 OK
if failure exit 1
lineout "AT+CPIN=0000"
input 20 OK
if failure exit 1
lineout "AT+CPIN?"
input 10 "+CPIN: SIM PIN2"
if failure exit 1
input 10 OK
if failure exit 1
exit 0
send an sms:
parameters: number "message"
(+49177... is the SMSC, replace by your provider's one)
#!/usr/local/bin/kermit +
set line /dev/ttyU0
if failure exit 1
set carrier-watch off
lineout ATZ
input 10 OK
if failure exit 1
lineout AT+CSCA="+491770610000"
input 10 OK
if failure exit 1
lineout AT+CMGF=1
input 10 OK
if failure exit 1
lineout AT+CMGS="\%1"
input 10 >
lineout \%2
output \26
input 100 ok
if failure exit 1
exit 0
of course I have some shell around it for failure handling (retries) etc
