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.
