On the AT type machines, there are a couple of ports
which are used to set or read the line control status.
These are used to set RTS and DTR, or to read DTS, CTS, etc...

I cannot find these ports (or their equivalant) in the old
Hardware manual.  Is this info available in the new ones?
I haven't got mine yet...

I just want to know where to look at the hardware level to see
if CTS or CD is set...

thanks
