Enclosed is some code I developed about a year ago for just that purpose. It
has been recently extended to handle binary streams as well as ASCII
character streams through the serial ports. The code is in two parts... The
first is C Source code for a small DLL. The second part is the CLisp FFI
interface code. It is small enough that it should be readily comprehensible
to anyone. Let me know if this helps out.
Note: This code was intended to run under Win/NT 4.0 but I have also used it
successfully under Win/95.
