But I spent a week changing motherboards for simplest worksation :-) IMHO, sio detection procedure may have options "STRICT" to do what it tries to do. If I just want to have 9600 console or mouse on sio device, I do not need all the troubles with detection. BTHW, SIO code itself works just fine on 115200. And please, exuse me if I said something in offesive manner. It's my pure English, not the intention. Best regards!
