Rx buffer increased to 128bytes. The code uploaded works only when I set interchar delay to 1ms and endline delay to 100ms. When interchar set to 0, it uploads without showing errors but the code hangs. Is there any trick how to push the serial to use Xon/Xoff actually? Is that an issue of CA-42 and a like?
