Abstract

The speed of asynchronous serial communications is detected by determining a duration of a data bit within an asynchronous data stream. The duration of the data bit is used to generate a clock frequency. The clock frequency is used to clock data from the asynchronous data stream into a register. The clocked data is processed according to an error indication.
