Description: Checks for a transmit packet. If there is no transmit packet, the clear-to-send flag is set and it exits. When valid input data is in the buffer, the receive interrupt is disabled. The data is loaded and a data packet is generated. Then the receive interrupt is enabled.<p>
Inputs: Void<p>
Returns:<ul>
