What is the best method to clear the keyboard buffer?
I know this method:

However, I'm not sure if it's the only or the best one. Are there alternatives, e.g., to prevent "overshooting" when scrolling through lists?

Is there a way to adjust the firmware?

Kind regards
Michael

I guess it depends on what you're doing but in my case, if there's a character in the RX buffer, I evaluate it with a SELECT-CASE. Use it or lose it.

The method you describe will work in general (PS2 keyboard/USB keyboard/console). All other methods I know are specific, either to USB or PS2...
In games we use a similar method to your second to keep the last valid key to control the game, the las one before the empty buffer responds with "".

Thanks for the confirmation, Harm. It's working great for me right now, too. I just need to figure out why it sometimes doesn't work so well and keeps running uncontrollably.

I vaguely remember that there used to be access to the keyboard ring buffer. I just wanted to make sure I hadn't overlooked anything.

Hi,
thanks! Unfortunately, I don't understand your answer. My question was about the "overshooting" when outputting lists (e.g., FM) controlled by the up/down cursor keys. I think that's answered sufficiently.

Kind regards
