Replace your serial consoles with something like a Cyclades that
allows use of public keys.

I don't think check_by_ssh is going to work since the ssh->serial
connection will probably not permit execution of a script and the
return of the exit code without a lot of work. Also it has no real
interactive support and it should like you need that.

An expect wrapper around ssh should do the trick and it can negotiate
the login prompt on the serial port as well.
