I see the eventcomm.c file in the synaptics driver:

https://gitlab.freedesktop.org/xorg/driver/xf86-input-synaptics/blob/master/src/eventcomm.c

And the ps2comm.c file could be similar to what I need. It read/writes serial to the PS/2 port.

I need to dig more, thanks for the direction. I need to make a decision tomorrow, but seems a new driver could be in order.
