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.
