Simple Ping Script

What are the errorlevels for the ping command?

I am trying to create a script that will ping a remote router, and in the
event it is non-responsive, will cause the machine the script is running on
to reboot without warnings or prompts.

Any help much appreciated.

Ping does not have any specific error levels. You need to check its output
in order to work out if the remote computer is responding, e.g. like so:

ping SomePC | find /i "bytes=" > nul && echo SomePC is responding.
or maybe
ping SomePC | find /i "bytes=" > nul || echo SomePC is not responding.

After some googling I have found mention of an errorlevel 1 for a fail and 0
for a result but they seem hit and miss. Certainly not something I am that
confident on trusting a reboot to.

The problem I see with the script, isn't with doing the logic. BUT, if you
are not able to get a response from pinging, chances are you will not be able
to send a remote reboot either.

It;s a local reboot - various reasons why but if I cannot contact a remore
router I want to bounce the local machine.
