I was told that no HP serial port does full hardware handshaking ...
bit 3 enables handshaking in one direction only (I don't remember which
one).  I would *greatly* appreciate someone telling me that this isn't
true :-)

I would almost *kill* for full hardware handshaking.  Does anyone have
the real scoop?
