I'm sorry to hijack you like this, but I've tried previously via proper
channels and it will not be fixed, as it's not a bug.

In classic IOS when channel closes your transport connection closes. That is,
you cannot open exec('command1'), exec('command2') to gather output of two
commands, the moment first one closes, TCP terminates.
I don't know if standard allows this or not, but to me it seems like bug.
Because that does not work, you're forced to open shell and do problematic
screen-scraping to determine when each command starts and stops.

Thank you and sorry,
