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.

I have a problem with my modem connection, KPPP tells me that I connect at 52000, but I looks that I never are able to get a data download rate higher then +/- 1kb.
I tested this with many websites, including some downloads from my own ISP, what normally gives a great download with my Windows 2000 computer.
I have a Micronet Shuttle 3000 external 56K modem, what connects with a serial RS-232 port. Micronet is to my know-how one of the manufacturers who is supporting Linux (www,micronet.com.tw change the comma) that is why I selected this relative expensive modem. (It was the most expensive modem offered to me)
My know-how about Linux is very limited; you can say that I’m very low on know-how. I hate to complain that the modem is not working right; as I’m not sure that this problem is related to a hardware failure.
I’m using Fedora Core 2 (Kernel 2.6.6-1.435.i686) on my second (old) computer what is installed on an Asus TUSI-M mainboard (SiS 630 chipset, Celeron socket 370, 1.3 Ghz, 256MB, latest “beta” BIOS).
If I connect to my ISP with the same account with my Windows 2000 computer there is no problem with the connection speed. So I don’t think that the problem is with my ISP.
The speed of my serial port sounds to me as a more likely source of the problem, the only problem is that I have no idea how to check the speed of my serial port or to change this speed of my serial port speed.
I solved the problem with my low modem data speed.
The first issue was that my serial port where set to 9600baud, I changed that to the maximum of 23400 with “setserial”. (Special thanks to AAA for pointing me to that direction)
Second I did some research on which chipset was used in my Micronet modem, MS Windows 2000 was able to tell me that my modem was based on the Lucent 56k Venus PnP chipset. After knowing this I searched on Internet for the correct modem init string.
I found that the init string used in KPPP was totally wrong and after changing this to the right information the modem worked correctly on full speed.
