It turns out that mgetty does NOT like being run from a login session. I
guess the reason it couldn't set a controlling tty was because it already
*had* one... the one I ran mgetty from.
So, that gets back to, why wasn't it working when I was using it in
inittab? Well, it turns out that the agetty line I had been using (before
someone suggested I use mgetty) had set the modem's S0 register to 1. So,
as near as I can tell, the modem was answering the modem on its own
volition just moments before mgetty sent an "ATA" which, I believe, toggles
the online state (hangs up if off-hook, picks up if on-hook). Hence, the
two clicks, I guess. So, putting "ATS0=0" in the init line for that tty
fixed the problem.
However, this has *not* fixed the bizzare problem with pppd thinking I
don't have PPP support compiled in, even though I do.
Also, the person who suggested that I use mgetty seemed to think I was
kiiky for wanting to use uugetty. Well, if he's listening, I'd like to add
that, under mgetty, I *still* can't dial out on the modem that mgetty is
sitting on. The whole reason I wanted to use uugetty was that it supposedly
allowed for dial-in and dial-out without having to do the "inittab
shuffle".
Just thought you might like to know....
