How to make xy plotter controlled via computer serial port

Is it possible to make a XY plotter which would be controlled by a computer serial port instead of a dedicated processor as everybody someway or the other just do that no matter what version it is

LTP port yes, serial I doubt.
Was quite often done for the earliy CNC machines.
The "controller" was nothing more than the required hardware to use the LTP inputs to drive the motors and to send back endstop information or speeds.
