A method of automatic baud rate detection disclosed includes use of low cost hardware to detect framing errors, detect actual transitions in a serial transmission, and calculate transitions in the character received. A current baud rate is taken as being correct, too low, or too high as a function of a comparison between actual transitions and calculated transitions in combination with detection of framing errors. A binary search among conventional baud rates establishes a correct baud rate for a low cost automatic baud rate detection receiving device within three "sign on" character presentations.
