[rancid] Rancid submits random characters after logon - causes config read failure

[Neil Arnold]

That didn't work I'm afraid. I appreciate that it's not a simple fix when,
as you say, there isn't one you can test this on so appreciate your effort.
Running hlogin now results in this:

MPG_5406_G/F# ^[[42;118R

The console is essentially now dead. I can issue commands such as deleting
^[[42;118R and entering show config and it does nothing. I'm tempted to
just ignore these and go on without them but I know it's always going to be
a nagging annoyance that I'll want to fix.

Thanks,

Neil.
