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, then
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?
