Most Linux distributions include the UUCP application. Start UUCP with the command “cu -l [device] -s [speed]“, where [device] is the serial port you are using, such as ttyS0 (COM1) or ttyS1 (COM2), and [speed] is the speed of the serial console that you are connecting to.
# cu -l /dev/ttyS0 -s 9600
You may need to hit enter before you see the login prompt. If you see a bunch of weird characters, then you probably specified the wrong speed.
To exit, just type “~.“.
