i think i have to reduce to 4x oversampling. hope that will run stable
enough.
unfortunately, i have no error checking, as on one port, i have a terminal
which is used to configure the device, and on the other port, there comes
logged data which has to be compared to the configured pattern to generate
output sequences.
as the data logging device is 3rd party, i have no influence on it's coding,
i.e. i cannot add any redundancy or reduce the bitrate.
