From the tx: and rx: numbers there it looks like data is being sent and received on the port. I have no idea what fe:1 or brk:2841 means, mine does not show those. If you move the mouse then cat /proc/tty/driver/serial you should see the rx: number change after some seconds. If not, then I guess you have something different plugged into /dev/ttyS0.

A serial mouse (we assume Microsoft 2 button type here) has to be powered by the serial port to send data to the host. Also the parameters of the serial port have to be setup correctly (1200 bps 7E1), so the cat /dev/ttyS0 trick will never work.

Fortunately Slackware already includes a program, which does everything we need. Just do:

# /usr/sbin/gpm -m /dev/ttyS0 -t ms
Then try moving the mouse. You should see a moving rectangle (the mouse cursor).
