I am looking for a device that attaches between the RS-232 port on a computer (in this case a laptop) and a Serial device (in this case an old programmable logic controller) that acts as a signal buffer. I'm NOT looking for something that stores data, rather I'm looking for a device that will protect the port on the laptop from spikes as well as improperly wired or damaged ports on the PLC machines. I'm looking at making my own, with a ZIF socket so that a damaged buffer chip (probably a MAX232) can be swapped out quickly, but I don't want to re invent the wheel is a similar device exists. Thanks!
