Conversing with Telnet using DDE
In a DDE client/server conversation, Telnet can be used only as a DDE server. To use DDE as a server, you must first choose the Telnet DDE Server command on the Settings menu of the WyseTerm application. You cannot use Telnet as a DDE client to another application.
In order for a DDE client to establish a connection with Telnet, you must specify the following in the order listed:
- The server’s name (in the case of Telnet, htelnet).
- The topic it wants to have a conversation about.
You can represent this application-topic pair using the following command:
- Appname|topic
For example,
- Telnet|System
Once the client has established a connection, Telnet responds to the request transaction items issued. Some items return information, while other items perform functions. The most commonly used transaction items in Telnet include the following:
- request transaction items
- execute transaction items
Note:
Check all execute transactions using the ExecReturn request transaction item. - poke transaction items
