Hi g00r00

From the Mystic Guy YouTube channel I have the following question from Chros Schneider

[snip]

Is there the standard XMODEM CRC protocol available to use? The XMODEM-1k is not compatible with older 8 bit systems that I want to support but the
original XMODEM CRC is. If so, how would I implement it.

If you want to reply here I can paste the answer back to him on the channel
for all to see.

Thanks in advance for any feedback.

Best, Paul

Xmodem-1K should fallback to Xmodem-CRC if I am not mistaken but of course it has had very little testing since Xmodem is never really used by anyone.

If there needs to be a new Xmodem-CRC I can add that in for you, I just need
a way to test it.

Thanks :) I will pass this back to the chap and let you know any feedback.
