ok, i think you've established that the hardware is working properly. the fact that you can get IC to boot and talk to the board is strong proof of that. the zterm test demonstrates that the mac can send chars out; the IC example proves (...) (26 years ago, 28-Jan-99, to lugnet.robotics.handyboard)
