As i correctly understand mxser use formula:
+-
| base/baud, baud <> 134
div = |
| 2*base/(2*base + 1), baud == 134
+-
Jan's driver use:
div = (base + baud/2)/baud
What is actual
div = base/baud + 0.5
That seems more correct for rounding....
In additional:
1. You should use 921600 value instead of 912.600.
2. Interface is asynchronous and (IMHO) data could be transfered in a
range of frequencies (BAUD +/- RANGE%)
