	Anyone out there who can give the specifics on connecting
a Diigital LXY22 w/printronix serial connection to a tty port on a
Sequent Symmetry? Currently, I am crossing 2 and 3, and 8 and 20, on
the pins and using the following printcap:

lxy22|lp1| Digital LXY22 in room 115 (CSUN5 Client room):\
	:lp=/dev/ttyhf:\
	:dn=/usr/lib/lpd:\
	:br#9600:\
	:tr=\f:\
	:fc#0177777:\
	:fs#0001421:\
	:of=/usr/lib/lpf:\
	:sd=/usr/spool/lpr/lxy22:sh:pw#80:\
	:lf=/usr/spool/lpr/lxy22.log:\
	:af=/usr/adm/lpr/lxy22.log:

	The current problem is that the 2k buffer on the printers
serial card seems to be getting over-written (overflow light on back
of serial card flashes a second or so after transmit, in addition the
error ligt come on and stays on) after printing 20-30 lines.  Hence,
no-flow control (I guess). Anybody know how to make this work?  I can
toggle the RTS/CTS by hand at roughly 1 second intervals (via a
breakout box) and get the printer to work so I am relatively sure that
the proper flow-control is just not getting back to the tty driver.
The ack/nack jumpers on the board seem to be set properly 0x11 and
0x13 respectively, so should not the tty driver be responding to
x-on/x-off (it does appear to be)?
	Any suggestions would be greatly appreciated.
