See 'man xorg.conf' and a description of an InputDevice section.

In practical terms drop into /etc/X11/xorg.conf.d/ a file named,
say, 01-mouse.conf with something like this in it

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "mman"
        Option      "Device" "/dev/ttyS0"
        Option      "ZAxisMapping" "4 5"
#         Option      "Emulate3Buttons" "no"

adjusting protocol, device and options as required.  Many years
passed from the last time I even seen a serial mouse but in
principle that should work.  Hopefully.

If you want/need a mouse on a text console then gpm is using
a configuration in /etc/sysconfig/mouse.
'gpm -m <device> -t help' should give you a list of various
"candidate" protocols (or maybe your mouse came with some sort
of documentation?).
