I have Linux (Red Hat 7.0) set up to provide a firewall between my home network and the Internet (connected via ADSL). I am trying to avoid buying another monitor since the firewall requires very little care and feeding. I would like to connect the serial port on one of the protected machines to the serial port on the firewall machine. Clearly, I need a null-modem cable. The idea is to use a terminal emulation program to login to the firewall machine. So far, I am unable to get a login banner to apprear on the terminal emulator window. The serial port on the firewall machine is ttyS1. Using the stty command, I can confirm that the baud rate, parity and so forth. How to I configure the port to output a banner and permit login? Thanks in advance, Russ
There is a good serial port How-To that covers the details of setting up your serial ports.

At risk of not knowing why you wish to connect via serial port, why not just connect via SSH, since you already have the network connection? Enable SSH to only accept connections on your home network numbers, and if your IP masq''ing is correctly set up, it would not be a security risk.
