From a3c9607200fa5d73b5ca5d98520f8b3ed827bcad Mon Sep 17 00:00:00 2001
From: brian <brian@FreeBSD.org>

Subject: o Fix uptime for direct connections. o Style police o Make hangup
 abort the current connection, not   necessarily exiting (-auto/-ddial). o
 Trap HUP and INT during DoChat and abort the   connection attempt.  This
 means you can now   type "dial" and change your mind with ^C, or   HUP the
 process to stop it dialing.

Slapped into doing it by: Chuck Robey <chuckr@glue.umd.edu>
