Details
Only one on_ser_data_sent event will be generated each time after the ser.notifysent method is invoked. This method, together with the on_ser_data_sent event, provides a way to handle data sending asynchronously.
Just like with ser.txfree, the trigger you set won't take into account any uncommitted data in the TX buffer.
