As for the previous stuff on modem signals and so on, I was caught in a small lie, yes. Properly, it isn't right to hook to DTEs together with a crossed cable. But I'm willing to cheat on that one. I'll let the rest of the RS-232 stuff rest unless we really want to revive that thread... As for the VT525, yes, it is correct that it's just a base unit with no screen or keyboard. It has a normal VGA connector for any VGA screen on the back, along with two MMJ connectors and two DB-25 connectors (unless my memory fails me). As for colors, well... The VT241 and VT340 have no way at all to select colors for text. You can, however, select that different attributes, such as bold and so on, instead be rendered in other colors. And the VT525 can do that as well. So it is as compatible with the older terminals as much as is possible. But, people might say, I have seen output in different colors on the VT340... Yes, you can do output in all colors on those older terminals. The problem is, you need to switch to REGIS to do that. Ie, you do that when playing around in graphic mode, which the VT525 don't have, so there is no way it could do this in a way that would be compatible with the older color VT terminals, with less than implementing the full REGIS stuff. So, in the end, implementing the ANSI color codes was the only reasonable way to get colored output on the VT525, and it is nice to have... I like playing Beyond Zork with color and primitive graphics on my PDP11... :-) Johnny
