Subject: Re: [PATCH 0/2] braille: nbcon: Allow using a serial driver converted to nbcon API as a Braille console

Hello,

Petr Mladek, le mar. 22 sept. 2026 09:25:56 +0200, a ecrit:

That is actually expected: braille displays don't show the whole log of
what was printed, it only shows the last print. Getting it printed on
each character output is expected if characters are printed one by one,
the device will show the text as it gets printed.

Thanks for fixing this!

With regards,
Samuel
