Of course you are correct! I repeated the process (unplugging the cable
to simulate the failure of the comm port) and found that it detected the
spybot through the USB Tower; then when I attempted to download the
program, it activated the USB Tower and transmitted something (a couple
bytes, most likely)... but definitely not a program. I am guessing that
BricxCC transmitted the "stop program" command prior to calling NQC for
the program download. However, I received no error message or
indication that it failed, other than Not hearing the confirmation beeps
from the spybot.
Serial/USB tower support for spybot program download would be a great
feature for a future release!
