Trace - trying to trace ("AT!Rx", "AT!Lx" commands) 2N® StarGate or 2N® BlueTower responds "BUSY".

  • The gateway allows only one trace to run at a time. A "BUSY" response means a trace is running on a port other than the port you are trying to run the trace on.
  • Use the "AT!RX" command to end a running trace on
  • Use "AT&U" command to display active port with active trace
