That's not enough. You must be running either 3.5 or 4.0.3 of SunOS. I have a TI-800 printer running at 9600 baud on ttya, which needs XON/XOFF since it prints at about 200 cps. It worked just fine when I first got my system (running SunOS 3.5), but failed when 4.0 was installed. Explicitly setting the 1 in ":fs#06021:" in printcap helped, but not much. The 4.0.1 patch tape had no effect. The problem was finally fixed after upgrading to version 4.0.3 of SunOS.

I was never able to get XON/XOFF to work proberly with my NEC LC 890 PostScript printer. I'm running Sun version 3.5. It seems like the sun never sees the ^S from the printer. My final solution was to set the printer at 1200 baud .... ie spoon feed it. My printcap currently looks like: ps|cat|troff|lw:\ :lp=/dev/ttyb:sd=/usr/spool/lpd:rw:\ :fs#06021:xs#40000:\ :tf=/usr/local/bin/pscat:\ :br#1200:mx=0:sh:lf=/usr/adm/lpd-errs:\ :pw#80: If I even think about increasing the baud rate to 9600...the printer looses output. If anyone out there knows a solution to this I would appreciate it. Joe

[...] >Joe Your problem is most likely the printer not sending XOFF. I see no problem with your printcap entry. I'm not sure if it will help, but I've included the printcap entry we use on our HP pen plotter which needs XON/XOFF to run at 9600 bps. # # HP pen plotter, connected locally # hp|hpplotter|hp7550A|Hewlett-Packard pen plotter in 1E404:\ :lp=/dev/tty02:sd=/usr/spool/hp:\ :lf=/usr/spool/hp/log:af=/usr/spool/hp/acct:\ :br#9600:fc#0377:fs#0221:mx#0:\ :rw:sh:sb:fo:\ :ff=\033.J\033.P1\:\033.T\:\nPG;\n:\ :of=/usr/local/lib/vp/hpfilter: # Note that the HP 7750A can be programmed to use XON/XOFF by sending the sequence "\033.P1:" or by front panel selections.
