Abstract:
A method of detecting data communication property which is applicable to a device for receiving serial data and transferring the received serial data to a connected universal asynchronous receiver-transmitter, said method comprising:receiving the serial data; discriminating whether the serial data include an AT command; detecting data communication property including baud rate of the received serial data, parity type, and data format, based on the received AT command; generating a clock signal for receiving the serial data based on the detected baud rate and supplying the generated clock signal to said universal asynchronous receiver-transmitter; setting the detected data communication property to said universal asynchronous receiver-transmitter; monitoring whether the serial data is received while measuring a time period from a receipt of a start signal; and quitting the baud rate detection when the measured time period exceeds a predetermined time period.
