Logging to Disk
  I have been logging EAS events to disk for well over 4 years now.  I simply use and old computer with DOS 6.22 and a communications program in capture mode.   I  wired a Comm port on the computer to a serial port on the EAS box set to 9600 baud.   This system works well for me.

There are several programs available that do the same job, possibly in a more elegant fashon.  I have not reviewed them nor endorse any of them.
  easfc                         Freeware available from bnet.
  EASWatch              Freeware available from bnet.
  Scaptur3                  Freeware available from bnet.
  EAScriber Pro         A bit costly but it appears it can handle multiple boxes and can be networked.
