I have recently been victimized by either a power line and/or telephone
line glitch which took out my modem (Hayes Smarterm 1200) and my serial
card (CCS 7710). Having repaired both, I need advice on protection
devices to prevent a reoccurance. (Murphy says lightening will strike
twice.)

I recall seeing an ad for a power strip that contained filters for
both the power line and the telephone line. 

Does anyone out there have knowledge of these protection devices?
Do any of them actually work? I would appreciate any recomendations or advice.

If your modem gets zaped by glitches, check that protector block where the
telephone line comes in is properly grounded and that the carbon blocks are
in good shape.  Inspect the blocks by removing the two bolts on the
protector that appear to do nothing.

After having lost two modems to lightning this way, I found that the Telco
did not ground the protector when my phone line was installed. Ameritech did
reimburse me (after a bit of a delay) for the modem repair charges.
