NQC will first attempt to 'ping' the RCX, but if this fails I'm pretty
sure it will give up completely. However, each command that is sent is
retried several times (with increasing timeouts for each try) until an
acknowledgement is heard. Its possible that quick success on the 'ping'
leaves the timeout too fast for later on, but this shouldn't really be a
problem since the later packets use retries and increasing timeouts as
well.
Its all very strange. Can you send e-mail me the trace when using the
verbose option in a failure case?
