Hello People,

does the Armmite F4 works correctly with the Ascii VT100 Terminal Emulator?

The Editor looks Strange:

Set
OPTION DISPLAY 24,80
in the F4 to match the settings of the ASCII terminal.

Edit. Assuming standard VGA monitor, otherwise:-
"VGA can display 24 lines x 80 characters or an extended resolution of 36 lines x 80 characters
Composite video can display 18 lines x 48 characters (PAL) or 15 lines x 44 characters (NTSC)"

hi,
it looks like the F4 firmware is sending an escape sequence of the form:

esc [38;2; red; green; blue; m

to try and set the foreground text colour directly, bypassing the standard colour palette. this is something that geoff's 'ASCII Video Terminal' does not in any way support, and way beyond the normal set of VT escape sequences that can be relied upon as being universally supported.

this is a classic example of why, when deciding upon escape sequences to use, one should always try to work with the minimum set possible to achieve an acceptable appearance

cheers,
rob :-)

@phil99: OPTION DISPLAY 24,80 is the default on the Armmite F4. I have never changed it.

@robert.rozee: Ok, i understand. So, the only possible way to fix it, is to change the behaviour on the Armmite?

Try
OPTION COLOURCODE OFF
That might stop the undesirable codes being sent.
