Here is the quick and dirty script (please, no flames about using csh, I am
just a professor) I use to have the VAX (4.2 BSD) call me at home. It works
with a DEC DF03 modem only (/dev/ttyi1), and observes the tip/uucp locking
protocol. I have my own cron and crontab, and schedule calls from there. The
Burlington area phone company has gone to measured service for everybody.
