39 * Note 1: The actual baudrate of the Cyrustek ES519xx chip used in this DMM
40 * is 19230. However, the WCH CH9325 chip (UART to USB/HID) used in (some
41 * versions of) the UNI-T UT-D04 cable doesn't support 19230 baud. It only
42 * supports 19200, and setting an unsupported baudrate will result in the
43 * default of 2400 being used (which will not work with this DMM, of course).
