Subject: Need help with Rainbow printer(LA50)

       I just got my hands on a DEC Rainbow running CPM, (no doc of course),
and am running into trouble getting the printer (LA50) to work.  It seems to
be overflowing its' buffer at 4800 baud...dropping it to 1200 just delays the
data overrun.  Does the Rainbow use XON/XOFF ??? or does it use the BUSY/OUT?
What about parity ????  Can anyone help ?

                                       Thanks,
                                       Mike Romaniw
