  • Exactly! Well done!

    "but wat can i do abt it???"

    Well, you need to keep thinking! These are exactly the types issues that you will always need to address as a fundamental part of any programming task!

    Three choices should be obvious:

    1. Ensure that you process each character quickly enough to be ready before the next one arrives;

    2. Provide some way to quickly store the data as it arrives, so that you can process it later, at your leisure. This is known as buffering.

    3. Devise some scheme - or "protocol" - so that the microcontroller can tell the PC when it's ready to receive more data. This is known as Flow-Control or Pacing.
