Comments

A short break is a continuous Low on the TXD output for a duration of more than one frame transmission time M, where:

    M = startbit + data bits (+ parity bit)+ stop bit

A long break is a continuous Low on the TXD output for a duration of more than two frame transmission times plus the transmission time for three additional bits (2M+3).

A extra long break is a continuous Low on the TXD output for a duration of more than three frame transmission times.
