Preventing Idle in telnet

[Robert E. Huebner]

Looking for advice on how to solve the following problem in UNIX:

I need to find a way to alter telnet so that it will automatically
send characters periodically if the user is idle.  The specific case
is one where I am using telnet on a Sun to connect to a remote Multics.
The Multics has a "feature" which automatically logs me out if idle
time exceeds 30 minutes, even if processes are running.  Is there some
way to have telnet type a ^G sequence or something whenever idle time
exceeds 25 minutes?  Or is there a more elegant solution to this
problem.  I have no Multics experience, so I'd like to make the fix from
the Sun/telnet end of things.

Thank you for your time,
