OpenSSH with "resumable" functionality

[Misha Koshelev]

Dear All:

I was wondering if it might at all be possible to have the following functionality in OpenSSH:
(i) upon "timeout" of connection (say 2-5 seconds) disconnect
(ii) keep trying to reconnect
(iii) upon reconnection, resume session exactly where started

I realize GNU screen solves (iii), although I am interested in a slightly different purpose (nxssh vs openssh).

However, I am confused as to (i).

Any help much appreciated.

Please reply-all

Thank you
Misha
