Hello
Up until yesterday my nephew has been using the Xircom USB to Serial adapter on
an iMac (Blueberry 350 ) with MPW NQC quite successfully. Now NQC seems to be
able to transmit via the adapter (the green data light flashes on the adapter
and on the IR tower) but cannot receive the confirmation from the RCX which
results in a "no reply from RCX error". If anybody has had a similar experience
and managed to correct it I would sincerely appreciate hearing what steps you
took, otherwise it looks like I'm going to have to cough up about $70. for a new
adapter.
If the latter proves to be the case, has anybody had any experience with either
the Micro Connectors Serial to USB adapter or the Keyspan USB Twin Serial
Adapter? I did notice that the Micro Connectors adapter is RS-232 compatible and
the Keyspan adapter provides two RS-422 ports. As I believe the IR Tower is RS-
232 would that mean that the Keyspan adapter is incompatible with the Tower?
Thanks
Tim Goodwin

| (...) "no reply from RCX" is probably not an adapter problem. My first guess would be that the RCX doesn't have firmware loaded (If you see "00.00" on the display, firmware is loaded, if you just see an icon and "1", then it isn't). Second guess (...)
