I think the problem with any serial protocol is DC signalling, which is vulnerable to surges, a solved by an ethernet connection. I recently lost three serial ports in two computers due to a surge, one of which was connected to an APC UPS. (A SmartUPS 700) It defeats the purpose of a UPS somewhat, if it destroys your hardware. I've never heard of "power surge insulators," and a web search turns up nothing. Are these specific to serial connections? Could you supply more information and maybe some web site links?
