Hardware handshaking "model" for lp

[utzoo!decvax!duke!harpo!npoiv!npois!houxm!houxa!houxi!houxz!ihnp4!ihnet!turek]

I'm in the process of interfacing a TI model 810 printer
to the LP print spooler.  Unfortunately the 810 does
hardware handshaking via the Reverse Channel or Data
Terminal Ready leads instead of XON/XOFF to signal that
the input buffer is full.  Therefore before I go through
the trouble of understanding the tty driver and how to intercept
the necessary control information.... Has anyone interfaced
a similar printer or device to the lp subsystem or the a
unix tty port.  Any help is appreciated.
