[comp.unix.i386] SCO uucico xon/xoff setting

paul@actrix.co.nz (Paul Gillingwater) (07/14/90)

I've RTFM'ed, but can't find an easy way to do this:

Enable or disable Xon/Xoff on the port that uucico is using to call out
on.  Yes, I know about (stty ixon ixany; sleep 10000) </dev/tty1a but
that's a bit of a kludge.  What's the correct way to do it?

Sorry, specifically when are you trying to switch the flow control on the line?

The problem, we found, was in the serial MUX being used between the 386
with SCO and the HP9000 mini.  The serial MUX was set up to do strict
in-band flow control, i.e. Xon/Xoff.  It received some blocks at 9600,
which soon filled its buffer -- so it asserted Xon, which was ignored by
the SCO uucico.  I believe uucico turns in-band flow control off.  I was
wondering how to change any other bits of uucico, e.g. out-of-band flow
control, such as RTS/CTS.

Both uucico and cu will set ixon to what they require without regard to
the previous settings.  If you are having a problem, it might help to
verify that the modem is not eating the Xoffs sent by the DTE.

The most common and desirable program to respawn to the communication
line via inittab is /usr/lib/uucp/uugetty; since this allows the same
line to be used for both incoming and outgoing calls.
