It should be easy to create a script that runs from 0 to 9999 or
whatever and tries every one out.   A simple for loop in any scripting
language would do that.   The only thing is to know how to send the
password to whatever it is that needs it and to read the response
to know if it worked.    If the system locks out after a certain
numbers of errors, then you will also have to add some waits to
get it past those delays.    I have no idea how to send to the
device you are speaking of or to read its response, but probably
something to STDOUT and from STDIN would do it or you may have to
open a pipe.

If it is more tha 4 digits, set the for loop to go another one or two.
Running it could take a while if there are lockout waits - in the
order of weeks.
