Add auto-reconnect option

[smpartlow]

I often use tnz.zti to connect to my host systems, replacing IBM Person Communications (PCOMM). I would be nice to have it auto-reconnect to those systems after I lose connectivity (or logoff) such that it's ready for me to log in again. Right now I have to type in goto <hostname> each time I am disconnected.

To add a little more doc: I have multiple host systems in a session (set up via a --rcfile with multiple goto statements in it) and so when I start up my machine again they all went away and I get (actual host names redacted):

ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'HOST1'
ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'HOST2'
ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'HOST3'
ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'HOST4'
ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'HOST5'
Session: NONE>

It would be great if I could issue a simple goto again or some other command like reconnect to get them back up again. Or better, let the sessions remain (disconnected) until I go to them again and they try to reconnect at that time.

I think that auto-reconnect would be a great enhancement. In the meantime, for the case you mentioned where sessions are established by an rcfile and you lost all of them, you could enter source <rcfile> to re-establish them (<rcfile> is the name of your rcfile). It's not exactly reconnect as I imagine it since your current environment (i.e. variables and terminal size) will influence the re-establishment of the sessions, but it may be close enough.

FYI, I've pivoted my setup so this feature is no longer high on my wish list.
Instead of having multiple sessions in one, I switch to using terminal tabs for each session. That allows me to separate them into separate windows if I need to see them side-by-side. I also just noticed that Windows Terminal give me this reconnect message when it disconnects, which gives me the reconnect feature I wanted:

ConnectionAbortedError: [WinError 1236] The network connection was aborted by the local system
SESLOST = 'MYSES'

[process exited with code 10 (0x0000000a)]
You can now close this terminal with Ctrl+D, or press Enter to restart.

Hitting Enter restarts that session.
