DDE Topics Available in Telnet

If you are trying to establish a connection with the Telnet application, you must pre-specify all conversation topics at the beginning of a connection attempt. You can choose any combination of the following DDE topics in Telnet:

System Topic Request Items (HTelnet|System)—lets the client determine what topics are available and assess the format types of the messages. The System topic is a standard DDE server topic.

Terminal Topic Items (HTelnet|Terminal)—lets the client control the terminal emulation mode (ANSI-BBS, SCOANSI, VT220, VT320, WYSE50, WYSE60, or DG210) and other connection settings in the Telnet program. It also lets the client load previously saved settings files.

Emulation Type Topic Items (HTelnet|EmulationType)—lets the client make changes to the settings in the Telnet program. You can set all options available on the Property tab of the Modify Terminal Setup dialog box in WyseTerm. To view these settings, open WyseTerm and click Terminal on the Settings menu.

Page Topic Items (HTelnet|Page)—lets the client control the current displayable properties such as color and attribute settings that can be changed manually in Telnet in the Modify Terminal Setup dialog box. It also allows the client to retrieve blocks of characters from anywhere on the display screen.
