Does the OLPC have a serial port?
No. but it does have 3 x USB... and a sound card.
But since the sound card has been shown to have a DC input capability, it would seem that it could be used as an RS-232 serial port too. Just a little bit-banger software...
The output might not have enough swing to drive other devices, but the input should work. That would be a great capability... For backward compatibility with RS-232 devices out there... A good project for someone...
