-FrSky Telemetry is supported using the T6 pin (UART6 transmit). You need to set the following parameters to enable support for FrSky S.PORT
+FrSky Telemetry is supported using the Tx pin of any UART including SERIAL6/UART6 . You need to set the following parameters to enable support for FrSky S.PORT (example shows SERIAL6). Note this assumes the RC input is using default (ALT_BRD_CONFIG =0). Obviously, if using ALT_BRD_CONFIG = 1 for full duplex RC prtocols, you must a different UART for FrSky Telemetry.
