7.1.f – TX ACK Advance

Calculate: If you know that your application will not run into trouble with flow control or data flushing, you know what baud rate it uses, and you’d like to adjust the Tx Ack Advance to most closely approximate the timing of a built-in port, you can calculate the value yourself using this formula:

Integer ( (baud / (totalBitsPerCharacter * 1000)) + 0.5)

This will result in the host receiving the “transmit complete” message at approximately the same time the last character has actually been transmitted. Note: the total bits per character include the start bit, the stop bit(s), the parity bit (if any) and the data bits. So, an 8-bit character with one stop bit and no parity has a total of 10 bits.
