Mr Bob: Would it be possible to write a low level driver, that would take data from COM1, and make it appear as COM2,3,4... and likewise with outbound data, collecting from COMx and moving it to COM1? I realize that there would need to be a protocol, and I've worked that bit out already. The mystery to me, is how to create "virtual" comports. I think this is similar to how USB serials work, since there's no conventional uart hardware there. -- Dave's Engineering Page: http://www.dvanhorn.org Where's dave? http://www.findu.com/cgi-bin/find.cgi?kc6ete-9 -- http://www.piclist.com hint: The PICList is archived three different ways.
