Configuring DXTelnet
Configuration Steps for DXTelnet on PC "A":

1. Run DXTelnet.

2. Press ESC or click on Cancel to hide the Site List.

3. Go to the Configuration pull-down menu and select the "Links..." submenu.

4. In the "DDE Link to a Windows Application" section set parameters as follows:

EXE Name:     UDPSEND
Link Topic:    UDP
Link Item:      textin

5. Leave "Enable Link" unchecked.

6. Press the "Save" button.

7. Close DXTelnet.
Comments:

The "Enable Link" box is not checked when using UDPSEND.  By entering the parameters for UDP in the "DDE Link to a Windows application" section, you are already creating a link.  "Enable Link" would only be used in a single PC configuration to link DXTelnet to WriteLog using DXT2WL when the UDPSEND utility is not used.
