Introducing WyseTerm API
WyseTerm is a communications and terminal emulation program that supports ANSI-BBS, SCO ANSI, WYSE-50, WYSE-60, VT320, and VT220 (also supports VT220 7-bit or 8-bit, VT100, or VT52) terminal modes. WyseTerm allows a user at one site to access a remote host as if the user's display station was locally attached.
You can use the WyseTerm API to customize your WyseTerm terminal emulation settings by using DDE and OLE to create dynamic links between Telnet and any other application.
DDE and OLE are mechanisms that allow applications to work together. DDE lets the applications talk to each other: one as the server and the other as the client. In Telnet, DDE can only act as a server. OLE lets the secondary application communicate with Telnet and define a set of properties and methods in it. As a result, OLE gives programmatic access to Telnet components from high-level programming languages and application scripting systems like Hummingbird Basic.
Using DDE and Telnet
Since Telnet is the server, the client application must establish a communications channel with Telnet. Communication takes place on a topic basis. This means that Telnet sets itself up as the server for a defined topic. The client then communicates with the server on a particular item of that topic. Normally, the client requests data on a particular item from Telnet, or simply makes a request that does not require the return of data.
To use DDE as a server, you must first click the Telnet DDE Server command on the Settings menu of the WyseTerm application You cannot use Telnet as a DDE client to another application. For more information on using Telnet, see Related Topics below.
