8.10: How do I enable GNO to activate dialup access.
A#8.10: This question is not about using your IIgs to dial out to another
machine. It means that you're allowing other machines to
dial in to your IIgs running GNO.
The first thing you should consider is whether you really want
to do this. GNO doesn't have any user/group file permissions,
so as soon as someone is logged into your IIgs, they will have
read/write access to all of your files. Because of this, the
only layer of protection you have is dialup/getty and the security
of the password file (including how well all passwords are
chosen). There has been no known investigation into the security
of the GNO dialup/getty.
That said, the way to enable dialup access is through the dialup(8)
program. It is invoked as
dialup tty [speed [init_string]]
Normally this would be done at GNO "boot" time through the initd(8)
facility. Add the following to your /etc/inittab file:
# This enables the modem for remote dialup (_into_ the IIgs)
# when in multiuser mode (run level 2 or 3).
t2:23:rest::/usr/sbin/dialup .ttya 38400 ate1qs0=1s11=50\\r
Ensure you substitute the "38400" with a speed appropriate to your
hardware. Note that "14400" is not considered to be a valid speed.
If you are using a 14400 kb/s modem, you should use "19200" as the
speed setting.
See also Q#8.8 regarding initialization of the serial port.
You should also replace the initialization string with one suitable
for your modem (consult your modem manual). The one shown above
contains the following HAYES commands:
at (start command)
e1 local echo on
s0=1 auto answer on
s11=50 set touch tone duration to 50ms
\\r escaped carriage return (ends command)
