Does it? The prints I have show the 2 outputs with a factor of 4 (not 8) in frequency. > The M405 for the DP12-B serial port generated a clock that is 16x the baud > rate which is then divided by an M216 module. So for 110 baud (which you say you have), the M405 is running at 1760Hz? I do not believe that for one moment! -tony
