The com port run at 19.2 kb/s.
My pb is more the real time aspect: to see the plot changing in real time 
than the com aspect as the installation is already running with programs in 
c++.
The PC on which it is running is good enought
For me the interest is to migrate all taht on python to be able to make fast 
changes when it is of interest
