Description: Serial interface loopback test.
What is serialPortLoopback?
This boolean, when set true, puts this serial port into loopback test mode. Admins use this to verify the serial port's hardware is functioning correctly by looping transmitted data back to the receiver without an external device attached. For example, setting serialPortLoopback to true(1) lets an admin confirm the port itself works before troubleshooting the attached serial cable or device.
Examples
