Talk:VT220

Compatibility with modern hardware
I suggest adding a paragraph about compatibility with modern hardware. I have a VT220 attached to my computer. It is in my opinion something rather outstanding, that you can use 25 year old hardware together with modern hardware without problems. —Preceding unsigned comment added by Polemon (talk • contribs) 10:01, 21 April 2009 (UTC)

Generated character codes
The table recently added is rather confusing, as it doesn't (very obviously) differentiate between application and numeric modes, nor does it point out that F5 is typically BREAK and doesn't generate any codes at all. It's also unclear as to what the difference between VT100/VT220 modes are (as the terminal, IIRC) doesn't distinguish between them (as opposed to the VT52.)

ANSI standard
The intro paragraph calls the vt220 an "ANSI standard" terminal. This is wrong for so many reasons.

First of all, "ANSI" is the American National Standards Institute. There are hundreds of ANSI standards, so using "ANSI X3.64" (or "ECMA-48") would be more correct.

Secondly, the vt220 is ANSI compatible, but it's not ANSI "standard" in that it doesn't implement the standard in full.

There's so much misinformation around the use of the term "ANSI" with regards to ANSI X3.64 escape codes. The Wikipedia page for that is also 90% incorrect or irrelevant.

But at least there's plenty of content, right? Who cares about correctness when we have a big dumping ground of barely-researched garbage....? — Preceding unsigned comment added by 185.164.138.19 (talk) 02:16, 21 November 2017 (UTC)

Dynamically Redefined Character Set
The current test says "the VT200s allowed for another 96 characters in the Dynamically Redefined Character Set (DRCS), which could be downloaded from the host computer". The VT220 can only hold 94 printable character in this set. (The VT320 can do 96.) Lars Brinkhoff (talk) 16:03, 26 October 2019 (UTC)
