| Real | baudrate | | Speed of the serial link with the microcontroller (baud) |
| Integer | dataBits | | Number of data bits of the serial link (5 to 8) |
| Integer | parity | | Parity of the serial link, machine.UART convention: -1 = none, 0 = even, 1 = odd |
| Integer | stopBits | | Number of stop bits of the serial link (1 or 2) |
| Real | airBaudrate | | Air data rate (bit/s), radio frame 8N1 |
| Integer | txBufferSize | | Size of the transmit buffer (UART -> air), in bytes |
| Integer | rxBufferSize | | Size of the receive buffer (air -> UART), in bytes |
| Real | txDelay | | Fixed delay between the reception of a byte on the UART and its transmission on air (s) |
| Real | rxDelay | | Fixed delay between the reception of a byte on air and its transmission on the UART (s) |
| Boolean | halfDuplex | | The module is deaf while it transmits |
| Real | drawnFMax | | Highest frequency of the drawn carrier (fDisplay, plus deltaFDisplay in FSK), Hz |
| Boolean | warnSampling | | Warn when the output interval of the simulation is too long to draw the carrier |
| String | instanceName | | Component name, prefixed to the log messages |
