- I have a problem with configuring a serial line with handshake:
-
- Upon line failure, the process connected to the serial line does not die.

- This problem turns out to be a serial line problem. I tried it without the
- modem. The uugetty now runs on ttym2 and reads from a 9600 terminal.
- If I just power-off the terminal, I can see the DCD signal to become inactive,
- as requested for a HANGUP condition (described in serial(7), and analyzed
- with an interface analyzer.) The only active signals are now DTR and RTS.
- However, the process on ttym2 does NOT die. It is absolutely unclear to
- me how this can happen, because I thought that this would be the handshake
- condition...
