+1 to Tony for heading down the right path.
The rear DB25 serial connector is an A & B serial port combined.
Sun had/sold a special Y-splitter cable to use for the combined port.
Here is pinout information from sunhelp.org in case you want to make one for
yourself from scratch.
Plan B, either someone here has one they can give/sell you, or someone from the
Sun rescue list will. Or eBay, etc.
