Thanks to Mark Rivers, the bug in the code has been found. 

The special settings are related to the timing of the serial interface.

Stream device is fine, as long as you do not have to do special calculations of 
the PV value and some crazy bit shifting when building the string together 
with only two bit value as separator between the values and thing like that.

Many thanks for the tips and the help
