Might be asking the wrong question, it might be "what could be causing those bit 5 characters to be decoded & printed incorrectly?"  IOW, the code may be getting sent correctly but decoded incorrectly.  That the characters have a common denominator in the type box sounds suspicious.

Subject: [GreenKeys] Model 28 with a new problem

So I got the code bar 3 issue fixed as far as I can tell.  I can see all five code bars shifting back & forth.

But now there is a new issue...

A types as W

E types as Z

I types as P

S types as Y

U types as Q

3 types as quotation mark

7 types as 1

8 types as 0

Dash types as 2

STOP types as hashtag

Spacebar types as H

Line feed types as L

Now I was sleuthing the bit codes for all those keys and from what I see, the common denominator is bit 5.

On those keys, a bit 5 SPACE is being turned into a MARK.  On other characters where bit 5 is *supposed* to be a Mark, they are typing fine.

AND... it's not doing it on ALL the keys where switching bit5 from S to M would change the character.  For example, typing C does not change to V.

I can also see that these affected characters happen to lie in the center four columns on each side of the typebox (middle four for the FIGS section, & middle four for the LTRS section.)

The bit 5 code bar is NOT stuck. I can see it freely running back & forth between M & S.

So the question is: what could be causing a MARK to be sent on bit 5 in cases where it should be a SPACE?

Any thoughts, ideas or suggestions appreciated
