Chris Lewis, Harald Milz and Michael Staats have done excellent work on
mgetty to AIX. Since then, I have taken over and actively
use mgetty+sendfax on AIX for customer systems, and everything is very
well tested now.
On AIX, many people do not want to manipulate /etc/inittab directly,
instead, use some system administration tools (like ’smit’). To ease
mgetty installation on AIX, Michael Staats has provided a small
inittab.aix, that will help you setup your
inittab after you’ve run
make install. Just call it with the
name of the tty you’re modem is connected to, e.g.
I have received a couple of problem reports on AIX 4.1 where “suddenly”
the modem line stopped working and all mgetty reported were error
messages. If that happens to you, set
toggle-dtr no in
mgetty.config. AIX 4.1 doesn’t seem to like programs that fiddle
with the modem control lines.
Christoph Brinck (firstname.lastname@example.org) has also reported that it’s necessary to enable the “dtropen line discipline” for the serial line you’re using (whatever that may mean). This is done with the command:
chdev -l 'tty1' -a flow_disp='rts' chdev -l 'tty1' -a open_disp='dtropen'
or via the ‘chgtty’ part of
SMIT (but I think that’s the
default setting for new ttys anyway).
Hardware and Software flow control work fine on AIX 3.x and AIX 4.x now.
