libcurses keycodes wrong?

[NormanDunbar]

I might be wrong, it happens, but your 32 bytes might be the USB communications -- if your keyboard is or emulates USB of course.

I was indeed wrong. It seems, from Ben Eater, that USB comms is in 8 byte chunks, not 32.

Cheers,

but some implementations use only the first three or four bytes.

Apparently upto 6 keys can be pressed, but for some cheap keyboards, there are no diodes on the matrix, so errors are reported instead of the"n" pressed keys. I learned this just today.

Cheers,
Norm.

And back on the actual topic, I got a BBQL out to double check and to test the F? key behaviour.

An update to the patch is therefore.

Subject: [PATCH] INCLUDE_curses.h : correct keycodes

BACKSPACE
LEFT
RIGHT
UP
DOWN
F1-F5

all appear to be wrong in the file.

I am wondering if all the impossible keys should be pulled out, does any emulator emulate extra keys?

Interesting follow on to this, the libc for qdos-gcc already has these changes in it!

But whoever did those changes obviously got annoyed at some point.

Code: Select all
