40 * Note 1: The actual baudrate of the Cyrustek ES519xx chip used in this DMM
41 * is 19230. However, the WCH CH9325 chip (UART to USB/HID) used in (some

43 * supports 19200, and setting an unsupported baudrate will result in the
44 * default of 2400 being used (which will not work with this DMM, of course).
