automatic baud rate detection

<communications>

(ABR, autobaud) A process by which a receiving device determines the speed, code level, and stop bits of incoming data by examining the first character, usually a preselected sign-on character. ABR allows the receiving device to accept data from a variety of transmitting devices operating at different speeds without needing to establish data rates in advance.
