From b781c365ac728d64567834b5cf5d43a8e7727074 Mon Sep 17 00:00:00 2001 From: tilghman Date: Thu, 11 Dec 2008 23:35:55 +0000 Subject: When a Ctrl-C or Ctrl-D ends a remote console, on certain shells, the terminal is messed up. By intercepting those events with a signal handler in the remote console, we can avoid those issues.
