Both USART ports and the USB port accept input messages in all three supported protocols
(NMEA, RTCM and UBX) at the configured baud rate. Input messages of all three protocols can
be arbitrarily mixed. Response to a query input message will always use the same protocol as
the query input message. The USB port does only accept NMEA and UBX as input protocol by
default. RTCM can be enabled via protocol messages on demand.
In Auto Mode, no output message is sent out by default, but all input messages are accepted at
any supported baud rate. Again, USB is restricted to only NMEA and UBX protocols. Response
to query input commands will be given the same protocol and baud rate as it was used for the
query command. Using the respective configuration commands, periodic output messages can
be enabled.
