This is the dead man's switch for POCSAG signal reception.

To use it, you must make out the POCSAG number on which your provider sends out the periodical
Signal status messages. These are usually empty and reoccur every 4-5 Minutes on the network.

Adjust "sleep" command in "deadmanswitch" script to your needs (if signal repeats every 4 Minutes, it should
be safe to set the sleep command to 5 minutes, i.e. 300 seconds.).

Now adjust the .monrc file of the user running monitor like the following:

PAGER   0174760* [../../../etc/pocserv/signalguard/rearm > /tmp/monitoractionlog]  Keep-Alive

Given the POCSERV package being in place /etc/pocserv...

I have found that monitor derives path names relative to either starting path or user's home directory,
so I put a lot of ".." in front of the path in .monrc, so it finds /etc folder.
