Um... They should be /dev/tty00 (modem) and /dev/tty01 (printer); which
distribution are you using that you have ser0 and ser1?

Use tip and /etc/remote and a login script to connect to the modem,
pass it your init string, and then fail (so it disconnects), and call
that setup from rc.local. (I'd probably write a quickie program to
connect, write the string, and quit, but I think that's probably
a little too extravagant for most people...) You might take a look
at "dip"; it's a program for interacting with a serial port prior to
engaging SL/IP or PPP on the port. You can probably find it in
your local Linux source archive somewhere (sunsite.unc.edu springs to
mind), but I don't know if you can find a NetBSD port.

/etc/group. Put your name at the end of the line beginning with "wheel".
Jeez; my day job charges $60/hr tech support fees for help on UNIX
connectivity. I guess I'm just glad I can flame hell out of people
on this list; I suppose that makes it an even trade. :)

you have to know how to turn on before you can find them.
