Errors from standalone weather logging client will go to /tmp/metclient.error
file, /var/log/syslog, and an email will be sent to the operator. metclient
WILL NOT exit on any errors.

For the Field System. All errors are handle by the Field System and logged
like any other observing error.

PROBLEMS:
--------

If you get an error regarding the metserver and/or the metclient, that you
can't correct and you want to stop either or both of the programs you will
need to kill the metserver and/or the metclient manually. They will not exit
on errors.

 (This will give you the PID's for both the metserver and/or the metclient,
  whichever is running at the time:)

   prompt> log in as root
   prompt> ps -ef | grep met
   prompt> kill -15 PID

example:
   prompt> ps -ef | grep met

   prog     13526     1  0 16:39 ?        00:00:00 /usr2/metserver/metserver /dev/ttyS19 /dev/ttyS18
