How to clear serial port in linux via python?

Question

linux

Good afternoon
At the very beginning of reading the serial port / dev / ACM0 on which the Arduino hangs, no longer relevant data arrives.
How can I make the serial port clear when I run a python program

Answer 1

After opening the port, read everything from it with readall. And then do whatever you want.

Answer 2

I would advise in this case to add a data transfer initialization process, in which the arduina would give data only at the request of the script. Well, start-stop symbols.
