Hi All,

I have just upgraded a site from OSR 5.0.5 to 6.0.0. This has
gone mostly well.

I am now trying to set up DigiFax which they have been using for
years. I tried to set hardware flow control for the modem port
using stty -ortsfl ctsflow rtsflow but stty no longer recognizes
any of those three flags. They are still in the docs!

Anybody know where they went or what I may be doing wrong? How
can I set up hardware flow control for tty1A?

Thanks,
Rick Palen

You're doing nothing wrong. It looks like they're changing over
to rtsxoff and ctsxon, but these options aren't enabled in stty yet,
and the man pages for stty and termio haven't been updated.
Look at man asyc for other options to open the serial port
with certain modes already enabled, by using devices in /dev/tty*
and /dev/term:

# l /dev/tty1[aA]
crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/tty1A
crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/tty1a

# l /dev/tty00*
crw-rw-rw- 1 bin bin 3, 0 Jul 21 06:51 /dev/tty00
crw-rw-rw- 1 root root 3, 1 Aug 30 12:03 /dev/tty00h
crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/tty00m
crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/tty00s
crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/tty00t

# l /dev/term/00*
crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/term/00
crw-rw-rw- 1 root root 3, 1 Aug 30 12:03 /dev/term/00h
crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/term/00m
crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/term/00s
crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/term/00t

So, /dev/term/00t and /dev/tty00t are the equivalent of /dev/tty1a (terminal),
and /dev/term/00m and /dev/tty00m are the equivalent of /dev/tty1A (modem).

/dev/term/00h and /dev/tty00h have RTS/CTS (hardware) handshaking enabled.
(This is the one you're looking for.)

/dev/term/00, /dev/term/00s, /dev/tty00 and /dev/tty00s have XON/XOFF
(software) flow-control enabled.

Bob,

Thanks very much, that worked. Some of this software is old but
it just keeps on ticking!

the above made sense to me once i read the asyc (why is that not async?) man
page, but apparently not to the stock APC driver that comes with OSR6.

when running mkdev apc - to try and connect to com2/2a/2A/01h/01m, same
cable/UPS as had been running fine on 5.05, no port name seems acceptable
to the apc driver - all attempts return:

whatever_port_i_pick "is not currently set up for modem control (-clocal)"

asyc is the name of the driver. async is a different driver unreleated to
serial ports.

This will be fixed in MP2.

I haven't tried this, but I think that if you replaced /usr/lib/apc/portcheck
with this script:

#!/bin/sh
exit 1

it should short-circuit mkdev apc's test for whether a port supports modem
control. Be sure to use e.g. 1A or 2A, or you may find your system being
immediately shut down...
