Indigo can intercept and display the serial communication between the two parties

Pass Mode refers to the notion that Indigo will pass (or relay) data communication between two serial connections.  

To use Pass Mode you must use two serial ports on the host computer running Indigo and connect each port to the desired endpoints.

Pass Mode Configuration

When you enable Pass Mode, the following Pass Mode Configuration editor will be displayed.
