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?

NOBODY EXPECTS THE SPANISH INQUISITION

Ooops.

That shell I just posted about has to appear in /etc/shells, *and* getty's
not the process it's checking for.  It's init.
