void uart_endFrame ( )

End frame.

This function sends the FCS, that must be the end of a frame.

Returns: 1 on success; 0 on fail because of not buffer.

UInt8 uart_forwardCmd ( char * pBuf )

Forward command.

This function forwards the received or sent command to UART. On the coordinator this is used to collect the data, that can be stored or shown to an operator.

Returns: 1 on success, 0 on fail because of full UART buffer.
