Well, this link was interesting, so why don't i see what i can do:
--
Here's the pinout of the port, or at least I think it is. Using a serial cable should allow you to trigger remote interrupts, which is a big plus. However, I've never even seen a link cable so there's not much chance of experimenting. (The MIDI interface would also be interesting to play with.)
--
If I read the schematic right, this means the Communications Port is actually plugged straight into the SCI bus of the SH-2, both master and slave... meaning it's most likely fully controllable. (I belive theres a SCI.c somewhere around the compiller)
The plug it's the main problem... but there are test pads 15, 16 and 17 on that schematic that, if they're consistent between board revisions (they're on my board as well), can be soldered to an adapter or to stick the whole device inside, adding a ordinary port.
The cable might be built for serial purposes with a MAX232, or, what I find more interesting, to USB if we add a TI3410 to the mix(I just requested some samples for it). Ti3410 has a RS232 conversion and 3 I/O pins and is programmable hence looks like a perfect solution.
