John,
I'm not so sure it's just a matter of expanding the CASE statement. At a glance (not that I know Propeller assembler) it appears that the characters are stored as 7 bits within a single byte for each position with the 8th bit being the only attribute bit which INVERTS the video only. If this is so, then characters cannot be different colours, flash, be underlined, or become bold (bright aka Colour).

As to VT100, should be nothing more than expanding the central CASE statement after an ESC key is detected. I remember doing something like this for the LAVA video board. The keyboard input is tricky however, you will have to dig into Chip Gracey’s code (shown here).

Hi
I originally wrote the code for propIO on the N8VEM ECB board that I designed with Andrew Lynch. It was based on code by Vince Briel and his propTerm. Apparently a snapshot of this code was taken and modified. It was not complete so I would expect there are bugs you are finding. Wayne Warthen took my code and enhanced it by adding more ANSI escape sequences and verified. I plan to take that code and modify it for the S100 board (I am tired of the bugs too) and put proper Propasm for the I/O interface. I will not support the Hex display on the board but make it super fast and reliable with the current Console I/O board for the S100. I also plan to drop in code from kuroneko on the propeller forums to support either 100x50 or 100x75 character screen. It is 3rd on my queue of things to do, so if you can hang tight I will have a better driver in a couple of weeks or so.
Dave Hi Josh, I was able to follow along also. However, I am not sure how to do any programming. Now my concern is the following.
Many programs like word processors can be configured to work with the VT100 terminal. The VT100 is pretty common. So I think that the VT100 emulator on the console IO should be as compatible as possible. Even if the BOLD, UNDERLINE, and BLINKING are not supported I think that REVERSE VIDEO should have the correct escape sequence. According to documentation that I have the sequence should be ESC[7m.
I have also checked on the sequence for cursor control and everything seems to match with the sequence for the VT100.
How hard would it be to modify the .spin programs so that REVERSE VIDEO has the correct code?
Thanks,
Harold
