The data is written toEEPROM, then read back and verified.The string pointer parameters in the FT_PROGRAM_DATA structure should be allocated asDWORDs to avoid overlapping of parameters. The string parameters are then passed inseparately.If the SerialNumber field is NULL, or SerialNumber points to a NULL string, a serial number basedon the ManufacturerId and the current date and time will be generated.If pvArgs is NULL, the device will be programmed with the default data{0x0403, 0x6001, "FTDI", "FT", "USB HS Serial Converter", "", 44, 1, 0, 1, FALSE, FALSE, FALSE,FALSE, FALSE, FALSE, 0}© Future Technology Devices International Ltd. 2005
