In response to my query about how to implement a computer-to-terminal
dial-back scheme (terminal calls computer, terminal hangs up, computer
then calls terminal), I received a quick reply excerpted below:

Well, how simple!  My previous system didn't have "ct", and I had
never come across a reference to it.  But having received this
suggestion, I found that I do indeed have "ct", and it does exactly
what I wanted!!  

In my case, after I dial in and log in, I simply exec a script
which runs ct in the background, tells me to disconnect, and exits.
I disconnect the modem, and wait a few seconds, until ct calls me
back.  When modem connection is established, ct starts a getty, and
I can log in again!  Fantastic.  Thanks for your help, Willy!
Hope this is of use to others as well.
