The code above looks like it *should* work. What sort of behavior are you seeing?
Error values? On which device?
I seem to recall a little snag (bug) regarding setting the serial port speed during
SerOpen with the backward compatibility library... unfortunately I don't recall which
release of the OS had this bug... but you might try calling SerSetSettings to re-set
the baud rate after the SerOpen.
