Bug when using SSH on CatOS devices

[Dan Pfleger]

Hi Michael,
Don't know if anyone responded, but I've seen similar problems on older 
Extremes when it would omit EOL(s) at random places.

In this case, it looks like CatOS or the SSH client is omitting/munging the 
terminal's last \r\n based on your line:
   Switch> (enable) exitConnection to switch.foo.bar closed by remote host.

My solution for Extreme's was a bit of a hack, but it went something like 
the additional lines below.  Don't think it is worth putting in a patch 
unless this is a more common problem, but rather just a one off 
solution.  I forget if you need to put in a \n to make the file diff 
correctly or not, but you might need to re-output the line too if it is not 
100% consistent.

Hope this helps...
  TOP: while(<INPUT>) {
       tr/\015//d;
       if (/> \(enable\) ?exit$/) {
             $clean_run=1;
             last;
       }
       # Check and see if it was a "less clean" run.
       elsif (/> \(enable\) ?exitConnection to (\S+) closed by remote host\./){
             $clean_run=1;
             last;
       }
  }
