[general] dialup-line changes

henry (08/20/82)

Some minor internal changes have been made to our dial-in line setup.
Ordinary users should see no difference, except that it may sometimes be
necessary to hit RETURN once or twice to get the usual "U of T Zoology
Login:" message.

Note that it is not necessary to try dialing all three of our main
dial-in numbers (2579,2580,2581) -- dialing 2579 automatically tries all
three of them.  If you dial 2579 and you get a busy signal, they're all busy.
This trick does not work if you dial 2580 or 2581, so 2579 is definitely
the best number to dial.
