Can tip try more than one line for each site?

This is often a problem where a university has several modem lines and several thousand students trying to use them...

Make an entry for your university in /etc/remote (see remote(5)) and use <\@> for the pn capability:

    big-university:\
            :pn=\@:tc=dialout
    dialout:\
            :dv=/dev/cuaa3:br#9600:at=courier:du:pa=none:

Then, list the phone numbers for the university in /etc/phones (see phones(5)):

    big-university 5551111
    big-university 5551112
    big-university 5551113
    big-university 5551114

tip(1) will try each one in the listed order, then give up. If you want to keep retrying, run tip(1) in a while loop.
