[Simh] Tcp keepalive on hp2100 mux

[Quentin North]

Hi

I have noticed an issue with the HP2100 mux that results in telnet sessions that are unexpectedly dropped by the remote being left in an established state indefinitely and therefore clogging up mux ports even though the simulated system shows them as disconnected. I believe this may be to do with the HP2100 mux not using tcp keepalive.  Does anyone know if this is the case, and if so could you give me some pointers on how to fix?

Thanks

Quentin
