Queues a message to transmit on a J1939 channel's Tx FIFO, then enables the transmit bit in the channel's control word.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connect with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
module	: (Input) Module Number of the module to access (1 - [max modules for board]).
channel	: (Input) Channel Number of the channel to access (1 - [max channels for module]).
PGN	: (Input) Parameter Group Number.
priority	: (Input) Priority of the message (0 being highest and 7 being lowest).
destination	: (Input) Destination of the message (0 to FE, or FF to broadcast).
width	: (Input) word size of buffer.
buffer	: (Input) Pointer to the buffer containing the message. Buffer should be of type uint16_t* or uint32_t*
length	: (Input) Length of the message (in bytes).

Returns
