* Typically, the hardware performs a periodic poll for data that the
* transmit routine has set up to be transmitted. In cases where
* this polling cycle is not soon enough, this optional routine can
* be invoked to force a poll right away, instead. Proper use for
* each transmission for which this functionality is desired is to
* call the transmit routine and then this routine right after.
