Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Serial Electrical Test Equipment Breakout Gadgets, etc. While a multimeter (used as a voltmeter) may be all that you need for just a few serial ports, simple special test equipment has been made for testing serial port lines. Some are called "breakout ... " where breakout means to break out conductors http://oss.sgi.com/LDP/HOWTO/Serial-HOWTO-15.html from a cable. These gadgets have a couple of connectors which connect to serial port connectors (either at the ends of serial cables or at the back of a PC). Some have test points for connecting a voltmeter. Others have LED lamps which light when certain modem control lines are asserted (turned on). The color of the light may indicate the polarity of the signal (positive or negative voltage). Still others have jumpers so that you can connect any wire to any wire. Some have switches. output error Radio Shack sells (in 2002) a "RS-232 Troubleshooter" (formerly called "RS-232 Line Tester") Cat. #276-1401. It checks TD, RD, CD, RTS, CTS, DTR, and DSR. A green light means on (+12 v) while red means off (-12 v). They also sell a "RS-232 Serial Jumper Box" Cat. #276-1403. This permits connecting the pins anyway you choose. Both these items are under the heading of "Peripheral hookup helpers". Unfortunately, they are not listed in the index to the printed catalog. They are on the same page as the linux serial port D type connecters so look in the index under "Connectors, Computer, D-Sub". A store chain named "Active Components" may have them. Measuring voltages Any voltmeter or multimeter, even the cheapest that sells for about $10, should work fine. Trying to use other methods for checking voltage is tricky. Don't use a LED unless it has a series resistor to reduce the voltage across the LED. A 470 ohm resistor is used for a 20 ma LED (but not all LED's are 20 ma). The LED will only light for a certain polarity so you may test for + or - voltages. Does anyone make such a gadget for automotive circuit testing?? Logic probes may be damaged if you try to use them since the TTL voltages for which they are designed are only 5 volts. Trying to use a 12 V incandescent light bulb is not a good idea. It won't show polarity and due to limited output current of the UART it probably will not even light up. To measure voltage on a female connector you may plug in a bent paper clip into the desired opening. The paper clip's diameter should be no larger than the pins so that it doesn't damage the contact. Clip an alligator clip (or the like) to the paper clip to connect up. Take care not to touch two pins at the same time with any metal object. Taste voltage As a last resort, if you have no test equipment and are willing to risk getting shocked (or even electrocuted) yo
