Use the modem control port (the driver uses DTR when you refer to the
modem control port).  Wire the busy or ready line from the printer
(usually 11 or 20 on a 25 pin connector) to CTS on the computer port
(pin 5 on a 25 pin connector).  Change your stty to turn OFF xon xoff and
clocal, turn ON rtsflow and ctsflow ( stty <baud> -ixon -ixoff -clocal
rtsflow ctsflow ).  If you are using 2.3.1 make sure that you apply
the ctsflow/rtsflow fix from SCO Support.
