Noted -- I'll talk more about mgetty below.

OK, if I can figure it out :).

crw------- 1 root wheel 12, 1 Aug 31 19:29 /dev/tty01

Since I'm su'd to root, I'm assuming that's sufficient.  The error occurs
when I do this:

ghek# cu -l /dev/tty01 -s 38400
cu: open (/dev/tty01): Permission denied
cu: /dev/tty01: Line in use

(I'm basically doing this so I can issue AT commands to the modem.)

I've installed mgetty.  ps ax cheerfully claims:

 4113 ??  S      0:00.04 /usr/local/sbin/mgetty std.38400 tty01

...but the modem fails to answer the phone.  This could be an init string
problem, I suppose, but I thought the default string worked when I tried
this under linux.  (Of course, since /bin/login crashed under linux and it
didn't handle DTR properly, it didn't get me very far once the modem
picked up.)

Thanks, will do.

If anybody is using netbsd/macppc to answer the phone with either a login
prompt or a ppp session, by any method, I'd love to hear from you.
Thanks!
