Hi, I'm running an embedded system with a modem attached to a serial port (using the sc16is7x2 driver), and it seems that SIGHUP is not generated when the DCD line is dropped. I've verified that clocal is disabled and that the state of the DCD line is properly reported by termios (I'm using 'show comm' in Kermit, since it's easy.) However, if I attach a shell to the serial port (mgetty spawning login spawning bash), it doesn't hang up when the DCD line goes low. If I send a SIGHUP to the bash or login process via 'kill -HUP', it hangs up. Any ideas?
