Hello,
i have some strange problems with my DEC VT100-Terminal.
1st problem:
In Local-Mode, at some columns some characters were not correct displayed.
The first 3 columns are bad, then 6 are ok, then again 6 bad and so on.
Bad means, that another character instead of the typed character appears.
There is a "rule" for the bad characters: 0..9 -> 0, a..o -> ', p..z -> p, A->P -> @, P..Z ->P.
When typing in a "good" area, the character from the corresponding column 6 before will be overwritten by another "bad" character. This "new" bad character seems to be the lower 4 bits from the currently typed.
Example:
Step 1
Typed : abcpqr
Display: ' ' 'ppp
Step 2a
Typed : abcpqra
Display: a' 'pppa
Step 2b
Typed : abcpqrD
Display: d' 'pppD
char'D' is 44h, char'd' is 64h
Step 3
Typed : abcpqrD6
Display: df 'pppD6
char'6' is 36h, char'f' is 66h
This repeats in exactly the same way for each row.
2nd problem:
in Column 75 and 76 are always bad characters displayed. (Ɨ and the FF-Sign)
If i fill the complete screen with E (ESC # 8) everything except col 75 and 76 seems to be OK.
(see attached foto)
so it would be great, if somebody has an idea whats the problem...
Thans a lot
