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.

3) it shows that irq4 is serial, right?..wrong!!...it doesn't show it at all...it's silent...no usage means no show (most of the time), am I right there?
OK...then if at least 1 & 2 are right, then why does the port not communicate with a device that does work in windows(digital camera to be exact..all programs list the model but none respond)?
Maybe another brain might help me figure this out...I'd rather not continue the way I've been doing it, but it should be just like my gal's camera (sony usb)...hook it it and it at least acknowledges it.
The interrupt does not show up until the port is opened.
Just because something works on Windows, not really a guarantee it will work on Linux. Its a different program entirely with its own bugs and limitations. My camera still doesn't work with linux though the documentation says its supported. I've had better luck with a flash card reader than the usb software.
Well yes, the port's speed is suppose to be set within the application along with many other options. It wouldn't make much difference if you set the port's speed outside the program only to have it re-set when the application is started.
Could there be a cable problem? What's the program and where did you get it from?
Well, both cables work in windows. The camera is a epson photopc 550..I tried gphoto2 & gphoto with the same results. It could be a cable problem, as I was looking at the sub-mini plug, and noticed it was bent ever so slightly, but again, it works fine in windows.
Right now I'm trying to get it to work with Gthumb and Gnome in Ubuntu Dapper....I'm not at home right now, but when I get there I'll try the other cable just to rule it out for certain....
Ok, I looked up the cable for the epson photopc 550, and its a 3 conductor, which means only rx/tx and ground.
Interesting that the camera spec I saw is only 0.3 MegaPixels.
Just a thought, unless you Uber-like this camera it may be way easier to buy a new modern camera that is better supported.
The other cable is doing the same thing...I'm currently using a USB card reader for the memory card in the camera, and frankly, it's a 9 yr old camera...you're right, I might just be better off staying with the card reader or getting a new camera for my birthday or Xmas...
