Native redirection of Serial ports is supported in RDP connections only.

The RX-RDP, RX420(RDP), RX300 and LEAF OS firmware contain drivers for numerous USB-to-serial adapters, including adapters based on the popular Prolific PL2303, FTDI, CH341 chips, among many others. The device firmware creates a local serial port which the RDP client redirects then in the functional way.

The ‘change port’ command can be used inside the RDP session to verify whether the serial port has been redirected properly. Command output similar to the below will confirm a successful redirection:

The serial port redirected with native redirection will not appear in Device Manager of the remote desktop server.
