I got a serial cable for my CellPhone Ericsson R289LX. This phone has an internal modem and I was able to connect it to my laptop using the attached .inf file(http://www.pc-counselor.8m.com/bin/EriR280.inf). That's all I needed: The .inf file and a serial cable from the
cell to the serial port of my laptop.

The question is how I should change the pda registry in order to recognize the cellphone has en external modem? I found some information in MS web site about how to create a new set of registry keys for an external modem. But I
tried without any luck. Could somebody be more specific and help me in this
matter?

If you analyze the .inf all this file does is to change the windows register in the PC.

Thanks in advance.

Since the cellphone/modem is connected via the laptop's serial port follow this procedure. Click Start then settings then control panel. Double click on the modems icon. If no modems are already installed an Add New Modem window will open. If you already have a modem installed, click on the Add button. Let windows detect the modem (don't put a check in Don't detect my modem). Windows should detect a Standard Modem. Click on Change and Have Disk. Browse to the location of the .inf file.If windows can't detect the modem, try Add New Hardware wizard. At the window where it asks if you want windows to search for your hardware select no. Click on Other Devices from the list. Click on have disk and browse to the location of the .inffile.

You are talking about how to connect it to a laptop. I have it connected already that wan't my question. The question is how to change the registry in a PDA to use the cell phone in the same way I do with my laptop. I'm talking about PocketPCs.

Isn't your connection to an external modem different? Your PC should be connected to the modem, which in turn should be connected to your phone. What you will need is an adapter that takes the DB9 connector that formerly connected to your PC and changes it to an RJ11 which will connect into the phone line port on your modem. Try Radio Shack.

I have everything I need to connect the PocketPC and the cell phone. What does not exist is the driver. So I need somebody capable of read the .inf files for windows and tell me what to change and where to change the PocketPC's registry to make thiswork.

Your question is how to change the PDA registry. That cannot be done. the .INF files you reference are for the computer operating system and do not affect the operation of the phone. They control how the operating system interfaces with the hardware, in case your Ericsson phone. What I understand you want is to interface your phone with an external modem. To me this means that you want your computer to control a modem that will dial your wireless phone. In order to do that you would need the connection I indicated in my first reply. If this is not what you intended, please clarify.

Ok, the R289LX has an internal modem, so you can connet it to a computer and use it in a regular dialup. When you are installing the .inf file all it does is change the registry of your desktop computer, including the data for all the strings (internal commands) that the internal modem include in the cell phone need to work. All I need is the to know how to change the registry in my PDA (iPaq PocketPC 3635 with PPC 2002) and it will work in the same way it does with my laptop.
You have to takein consideration that the Desktop registry is a bit different than the PocketPC registry.
