[comp.unix.ultrix] lp26 off a cxy08 tty

bush@evax.arl.utexas.edu (Joe Bush) (12/20/90)

	I am trying to hook an lp26 up to cxy08 tty. I have managed
the basics and obtained some partial results. Problem is that rather
randomly the dhu fifo overflows resulting in a printer that hangs
until you take it offline and bring it back on (usually results in
lost data too). Still other times it will print long files without
incedent.
	Anyone familiar with this kind of problem and know a fix?  The
dhu (4) mentions the error but is unclear about how to rectify it. Is
there a way to adjust the input speed to the dhu drivers internal
queue (this seems implied by the dhu (4))? Also, anyone know the
correct pinout for the port? I suppose I may be missing the necessary
handshake.  Right now my breakout box is set to 2-2,3-3,4-5,7-7,8-8.
My /etc/printcap entry is:

lp1|1|test1:\
	:af=/usr/adm/lp1acct:\
	:br#9600:\
	:if=/usr/lib/lpdfilters/lpf:\
	:lf=/usr/adm/lp1err:\
	:lp=/dev/tty07:\
	:mx#0:\
	:of=/usr/lib/lpdfilters/lpf:\
	:sd=/usr/spool/lpd1:
	
	I have commented out any reference to /dev/tty07 in /etc/ttys.
I am running out of things to tweak. Any help, clues, pointers, etc...
will greatly appreciated!
