   > > [@fdcavalcanti](https://github.com/fdcavalcanti) probably it is 
happening because you are not using a terminal that supports VT102/VT220 ANSI 
escape sequence. Before this patch the serial driver was blocking most of the 
VT102 and VT220 byte sequences. This is exactly to avoid the serial driver 
consuming/blocking it blindly.

you need to filter out these sequences:

has had this problem as it is a clear issue when parsing, at least on Python.
   
   Exactly, this is the standardized way to pass these special keys. And you 
are right (just change the words order, hehehe) : "that is a clear Python issue"
   
   There is a Python library just to fix it:
