Gentlemen;
I have two Pentium Pros (200MHz) running 2.2.1. Both systems exhibit the same
problem.
Problem:
I have Epson DFX-5000 printers connected to each system via comm port 0 (sio0).
I had set flow control on via the stty command (stty -f /dev/ttyd0 ixon ixoff ixany)
Doing a stty -ef /dev/ttyd0 would display that the flags were indeed turned on,
and everything was fine.
However I rebooted both systems and now flow control to the printers is gone
and I'm unable to change it with the stty command again. At one point I did
actually change the bits after I changed the file permissions on /dev/ttyd0,
(see attached console log) but they kept getting
reset, and then finally I could no longer set the controls on. I have also
tried using the TANDEM bit in the /etc/printcap (see attached) but this
doesn't help either. Prior to the reboot I was not using the TANDEM bit, just
the stty commands.
I've consulted the documentation, Handbook sections 7.4, and still no go.
Do you have any ideas as to what I'm doing wrong or should be doing instead?
Thanks ahead of time for any advise you may have on this.
Gary Nelson

# This enables a simple local "raw" printer, hooked up to the first

# Remember, for further print queues you're going to add, you have to
# chose different spool directories (the "sd" capability below),
# otherwise you will greatly confuse lpd.
#
# For some advanced printing, have a look at the "apsfilter" package.
# It plugs into the lpd system, allowing you to print a variety of
# different file types by converting everything to PostScript(tm)
# format. If you don't have a PostScript(tm) printer, don't panic,
# but do also install the "ghostscript" package.
#
# Do also refer to section 7 (Printing) of the handbook. A local copy
# can be found under /usr/share/doc/handbook/handbook.{html,latin1}.
