Oh, Mike, that is so disappointing. A pure ad hominem attack? Really. Are you ready to admit your error?
Yes, VGA/SVGA is analog. Actually we agreed on that a long time ago, but it is not serial and you don't get it from a serial port like you told Jack (although the VGA's DB-15 connector does kinda resemble a PC serial port -- at least to HippseyGippsey). Why? Because serial is inherently digital (one bit at a time and all that). But you've been too busy flouting your ignorance to realize your mistake is that you misread Jack's response to you, made a little technical error (accompanied by the phrase "commonly used" to lend authority to your ignorance) and for some reason you simply can't admit it. Your attempts to cover it up revealed a whole universe of other subjects in which you are similarly ignorant.
No, Mike. I'm not wrong. Its the way you are trying to use of information you found on Wikipedia (probably using Google because you don't know what to search for directly) that's wrong. Even where you managed to get the content correct it was largely irrelevant to the subject (I'll remind you again: it's was PC video) -- I'm taking about your posts on lists of digital standards, modems and telephony, little hobbyist project breadboards, outboard A/D converters, etc. It's clear that you were just blindly searching for anything with analog and digital (you quit early searching on video, probably realized that wasn't going to help you) and came up with a bunch of unrelated data -- none of which are pertinent and all indicative of the fact you simply don't know what you are talking about.
I've told you what I think you should do here.
I'm done. Saturday is the day the Border Collies take me out and try to teach me to herd sheep and I'm tired of dealing with your pathetic attempts to dig yourself out of a hole. You can interpret that as "you won" if you want, but I think inside you know what happened here. I don't think you're stupid...I think you really could learn about this stuff if you wanted and I hope that you are young enough to get some formal education in computing or related areas because our country (hell, the world) needs more engineers and technicians building real tools that make life better for everybody. But I will tell you that it is hard work and there is no way around it. If you keep trying to fake your way through someone is always going to be around to expose you as the fool you are.
