The file FTDIPORT.INF contains entries that are used as the divisors for standard Baud rates. By changing these it is possible to alias standard Baud rates with non-standard values - for instance replacing 115kBaud with 512kBaud. Users would then set up the FT232R, FT2232 (UART mode) or FT232B to operate at 512kBaud by selecting 115kBaud for the appropriate serial port.
