After receiving slews of flame mail and many degrading posts regarding my post, I have decided to explain the situation for all you happy flamers. When I said "Standard RS-232 uses +/-5V DC" I was reffering to the voltage that it is capable of handling, not what is used as a standard voltage. I have built many serial interfaces and used 5 volts to serve as my communication voltage without problems. I also realize that +/- 9V DC and +/- 12V DC are usually a more stable level (and also recomended) but it will work just fine with 5 volts. Sorry for any inconvenience caused! -- >><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>><<>> | Respond to any of these adresses: | "Oh Lord...Ooooh you are so big..,| | -------------------------------- | So absolutely huge.
