Not that I know of, it was a long time since I have played it, I thought a null modem cable just simulated a modem, So I was just originating on one and auto-answer on the other, something must of have been happening because those errors were registering in the answering side.

the actual message is "Serial1: errors occurred: Framing 0, Parity 0, Overrun 10, , Break 0" This is the message that repeats while I am attempting to link both games, when the link begins the first message has overrun as 2, and then it follows as I wrote it above.
