Modsak Manual v3.11 - 7.1. Raw data tracing
To enable tracing of raw data, select the→ checkbox.
If raw tracing is enabled, all data sent or received is displayed as lines in the log. Each line begins with the time that the data was sent or received. In monitor mode, the time is followed by 'M' for tracing of data to/from the master, and 'S' for data to/from the slave. This is followed by the character '<' for incoming data or the character '>' for outgoing data, and then the sent or received data in hex.
