Try a null modem cable and/or get one of the serial port "serial port LED thingys" from radio shack or similar to determine if your pinning is correct. Generally you need a null modem cable between the two devices. Flipping pins 2&3 in the cable *should* at least get you the POST messages out of the sun box if this is the problem. If it is, you will need to do some more work to get a proper null modem cable. - Forrest W.
