Query: Bad BAUD rate?

I gave this ensemble a second chance. The keyboards and mice worked. The RF receiver, however converted keystrokes into unintelligible data at my computer's 2 serial P/S2 ports. Most keystrokes were ignored. Less than 10% were recognized correctly. Another 10% were badly misinterpreted and caused my computer to do incorrect things. It was as if the serial BAUD rate was off.
