The 16650 is still an 8-bit part, so extra databits would be useless. > Has anybody tried to use this card in their machine??? Did it work? > Does anybody know what a 16*6*50 is? How is it different than a 550? It's a 16550 with bigger (32 byte, IIRC) FIFOs. I don't know how you'd go about detecting it - what does the 'sio' probe have to say about it?
