When a parameter is unknown, the FPR does not only tell that it is unknown, it reiterate it, causing the following commands to fail, exit not to work and the model ends in a timeout.

> show xxx
Syntax error: Illegal parameter
> show xxxshowrunning-configall
Syntax error: Illegal parameter
> show xxxshowrunning-configallexit
Syntax error: Illegal parameter
> show xxxshowrunning-configallexit

My Idea would be to send something like "\e[16D\e[Jshow running-config all" to wipe the previous command out.
Alternative ansi escape codes : "\e[G\e[J" (go to the first char, then wipe) or "\e2K" (erase line).

I've got no success yet, but need to test further.
