You use it but, do you know where it comes from?

Hello people!!

This morning I was looking for information about Hayes modems, and comunication through serial port. The internet is full of information about this stuff and this fact made me think about one importan point: there is a lot of people, including me, thas uses many things and never wonder where, when, or why did all begin.

We use internet everyday. Instant messaging, e-mail, the web, all this services rely on modems. Today modems are very different of those ancient Hayes modems, but in essence they do the same function, they translate information from, lets say computer languaje, to a languaje understandable to comunication infrastructures. Don´t forget that if you can use common comunication infrastructures, you have a huge net available for cumputer comunications.

So here you will find some keywords you can search in any search engine (I would recommend Google , but is good for the internet freedom and health to try to use others), and some direct links:

Keywords: modem, hayes, at, dtr, rts, cd ,dcd

Enjoy!!!
