TTL pins
The Edubot had three pins for the TTL port and were labeled as Tx, Rx and BLK. The Fullsize RC has 4 pins and are not labeled other than + and B (the + is +5v).

Does anyone have (confirmed) knowledge of what the B and other middle two unlabeled pins are? Has anyone successfully interfaced with the TTL port on the fullsize RC? I've read some other posts and it seems as though some other teams are having trouble with the TTL port as well.

Thanks, Dave...
