What are you using netcat?

That would be awesome.  We used to write software at Computone to do
this.  We had to write a driver and that driver would enumerate COM
ports on the WinX side.  The problem we faced was that many apps would
not see pass COM4.  Good luck.  Not much free in that world on the Win2K
side.  It would be cool though.
