Subject:        Re: Serial Comms

If you are thinking of writing a windows app yourself, serial comms isn't
too difficult.

OpenComm
        Open COMM port, define buffer sizes
BuildCommDCB, SetCommState
        Configure COMM port (speed, flow control, etc)
ReadComm, WriteComm
        Read/write data
CloseComm
        Close port
See the compiler help files on these and related topics.

It is easy if you're doing polled reads.  Usually in a Windows app one would do
overlapped IO with multiple threads for read and write.  There is an ActiveX
 (OLE) comm control
that comes with Visual C++ that makes the task easier.
