I'm trying to connect to GPRS network through a serial port connected GSM modem.

When I call /usr/sbin/pppd call <peer_name> from the command line, It correctly receives and handles Ctrl+C from keyboard. But when I put the exact same command in an empty shell script (with or without the shebang at the top), chmod +x it and run it from the shell prompt, pppd starts to run but it totally ignores Ctrl+C key combination. Ctrl+Z works normally though.

This is the contents of the pppd peer file

nodetach dump connect "connect_script" disconnect "disconnect_script" /dev/ttyS0 noauth 

I tested another peer file which I had created to connect to a PPTP VPN server, with the same result. PPTP does not need a chat script, so I'm ruling out problems with chat command or serial port link properties.

OS is debian 7.

Any ideas what is happening here?
