Make their shell files (.cshrc) check where they're coming from.  Or give
them a secure shell which sees who's the parent process; if it's getty
they're coming in from a modem and you should can 'em.

Something like

#!/bin/sh

ppid=/bin/ps l $$ | awk '$1 !~ /F/ {print $4}'
if [ "$ppid" = "1" ]; then
  echo "so longer, sucker"
  exit(1)
else
  exec /bin/csh !*
fi

or at least along those lines.

You sure that printcap's still there?  The install does weird things....

Does your modem report call progress?  Like CARRIER 2400, PROTOCOL ALT,
CONNECT 38400 or whatnot?
