ABSTRACT:
In order to detect the format of asynchronously, serially transmitted character data using a command signal which includes a plurality of command character data, wherein the beginning of each of the command character data is identified by a start bit, and the character length of each of the character signals is L (a positive integer), the start bit is detected and a train of pulses generated to enable each of the character data to be sampled; the character signal is sampled and converted into a corresponding parallel signal; each of the parallel character signals outputted are ascertained; the number of character data received is counted and it is determined if a predetermined matching is achieved.
