  Log:
  MFC 1.57: fix the handling of the UCS_RXSTOP flag so that it always
  tracks whether or not the receive pipe is stopped. This ensures
  that we do not attempt to start the same transfer twice, and it
  allows ucomstop() to skip the restarting of the read pipe if it was
  not originally running, such as when called indirectly from
  ucomreadcb()
