How to use COM1 or COM2 in VFP 5
I want to write some data to a datacard machine through communication port,
I use function FOPEN to open the port
FOPEN("COM1", 12)
however, it always returns the value -1. And I can't find any other
information about
the communication port in the help file.
My questions are how to open a COM port in VFP 5 and how to write data to
it.
Thanks !
