Abstract:
A data communication system comprising: a transmitting station for transmitting data; a receiving station for receiving the data transmitted by said transmitting station; and a baud rate generator disposed in the transmitting station, the baud rate generator including first and second counters for counting clocks in a clock signal from a specified time to generate a first count and a second count, respectively, a decoder for setting a reference value in response to a set instruction signal, a first match detection circuit for detecting a match between said reference value and said first count to generate a first match signal, a second match detection circuit for detecting a match between said reference value and said second count to generate a second match signal, a third match detection circuit for observing a mismatch between said first match signal and said second match signal to generate an error signal upon the mismatch, and a control section for controlling said transmitting station and said receiving station, upon occurrence of said error signal, to re-transmit data starting from said specified time between said transmitting station and said receiving station.
