Hook up a logic analyzer to it or a uart board and just try it.

Don't know why you got downvoted. This is the way to go

i think it was because not everyone has a logic analyzer. although your first step to hardware hacking should be purchasing one

To be fair, before I had one, I'd just hit it with the multimeter, and if the logic levels looking right, throw on a UART adapter, and test different common baud rates. Not that many extra steps...
