I am running Windows XP SP3. When I get into the DOS mode The screen displays " C:/Documents and Settings/X(Represents my user name)>. I have used all variations of the "dir" command that I can think of but it stays locked inside of the above stated display. It doesn't recognize the "cd <directory> command. Has anybody got any Ideas?

Hi Ed,

That is quite strange, I have never seen that before. So you are saying you can't seem to type anything in the command line at all, or does it just not recognize the commands you are typing?

When I access the start menu and click Run and then type cmd I go to the dos screen. Normally you would think the screen would just display C: and the dir command would show every folder on the c drive. But instead of just C: It displays c:/Documents and Settings/ X(represents my user name>. Whatever variation of "dir" command I use it keeps me within the Documents and Settings folder. Somehow I need to be able to get the DOS screen to display the whole C drive.

Hi Ed,

It looks to me like you are just having trouble moving around the directories on the command line. Take a look through this library article about the command line. It should help you get started moving around. Let us know if you still have issues.

So Ed said:

But instead of just C: It displays c:/Documents and Settings/ X(represents my user name>.

Try cd ..

or cd ../ or ../..

.. backs you up one directory.

Thanks When I tried the command cd I kept getting an error message. I must not have entered the right syntax.

I have another problem! in the Devise Manager under Ports I show this; Prolific USB-to-Serial Comm Port(Com5). Under properties I see: Ports (COM & LPT), Prolific, Location 0 (USB-Serial Controller), This device is working properly. My DOS screen is as follows.

I have checked all of my connections and they are okay. Has anyone got any idea what's wrong?

I think you need to remove the /dev/tty and only use the COM5. Try and see if this helps.

Thanks again. This solved my problem.
