Re: RS232 card for PC with surge protection ??

[Dave McLaughlin <dave@xxxxxxxxxxxxxxxxxxxxxxx>]

Another option is to build your own buffer circuit from a couple of
MAX232 IC's on some veroboard. I did this in the past as I suffered a
similar problem.

Might be your cheapest option by far if you are handy with a soldering
iron.
