Odd project:

I have two devices that speak to each other via RS232. I don't know any of the settings, but I think I can guess, ar do a trial and error until I find the baud rate.

I want to build a device that splices into the wires that connects the two commumicating devices and reads the data that goes back and forth.

I am using a PIC 18F4550.

Is this possible? Any thoughts on how to do it or what problems I might face?

Cheers,

Sterling
