According to my Mach64 manual, the card uses the port address 0x2e8. It's also the address of sio3(COM4). Someone told me a quick fix. Remove the address from the list in sio.c. It works for me. I guess FreeBSD probes all possible serial ports, when you enable any of the serial ports. This causes the problem.
