Thank you for you advice, I already found this in google but no luck.
I tried sending the messages to ttyUSB0 but nothing is likely to happen. i tried the same with ttyUSB1 and i ended with an error:
Code:
Couldn't set tty to PPP discipline: Device or resource busy
here is the details.
i started reading on ttyUSB1 on one terminal window:
Code:
root@vostro1015:~# tr -s "\n" < /dev/ttyUSB1
on another terminal I issued the following commands.
Code:
root@vostro1015:~# echo -e "AT+CPIN="0000"\r" > /dev/ttyUSB1
Code:
root@vostro1015:~# echo -e "ATDT*99#\r" > /dev/ttyUSB1
Code:
pppd ttyUSB1 115200 nodetach defaultroute noipdefault noauth lock usepeerdns
Couldn't set tty to PPP discipline: Device or resource busy
is there any comments?
