The standard baud rate for AUTOSPEC is 68.5 Bd.
The parity dependent repeat transmission of the 5 data bits is easily recognized by ear for certain character combinations. The IDLE signal also has a distinctive sound.

10-Bit Bauer Code |
The Bauer code is used for error detection and correction purposes. Each code word consists of 10 bits. The five leading bits are a character of the ITA-2 alphabet and the trailing 5 bits are a direct repetition of the first five bits. If even parity is present, the last five bits are inverted before transmission.
The Bauer code can correct single bit errors and corrected characters are displayed in red on the screen display. Characters which have been found to contain more than a single bit error are represented by the underline symbol. Error correction may be enabled or disabled by selecting ECC (Error Correction Control).
