Hosts often have idle timeouts. If you don't send them any characters
on a Telnet connection for a certain amount of time (whatever the host's
idle timeout is), the host logs you out. The same thing might happen
in your router or firewall. One solution is to always "press a key"
at least once every xx minutes, where xx is the idle timeout.
A better solution is to use a Telnet client that will do this for you
automatically, such as C-Kermit 7.1:

C-Kermit's idletimeout-defeating feature is explained here:
