Flow control is hardware but VCTern won't transmit a NULL 0x00 because it
uses it at a string terminator.

What I am having trouble with is this "Variant" ???
Any examples of using with Visual C++ would be appreciated.

My first inclination would be to ignore the existence of MSComm. Just open the serial port
asynchronously and do WriteFile operations.

Hey Me? :) Perhaps this will help, it's a tutorial for C# but talks about
sending and receiving the null byte (and it's says it uses McComm.ocx) so
hopefully it's what you are looking for.
