'gpio' is General Purpose Input/Output. Circuit designers use them for
interfacing everything from simple electronic circuits to the insane. I
just noticed the pinout similarity with the 4501. I myself am quite
happy with the onboard serial, as I didn't like giving up my console
port on my 4521 in order to use my serial devices.
For what it's worth, I've built a device around my 4521 and will be
speaking on it here:
I highly doubt anyone is in the San Diego area on the mailing list, but
I will be giving Soren & Crew credit for an outstanding oem device then
