1.3 Embedded ICP Environment
Refer to the user’s guide for your embedded ICP and operating system (for example, the
ICP2432 User’s Guide for Windows NT) for software installation and setup instructions.
The user’s guide also gives additional information regarding the data link interface
(DLI) and embedded programming interface descriptions for your specific embedded
environment. Refer back to Figure 1–2 on page 19 for a diagram of the embedded ICP
environment. Running a client application in the embedded ICP environment requires
the basic steps described in Section 1.4
1.4 Client Operations
1.4.1 Defining the DLI and TSI Configuration
In order for your client application to communicate with the ICP’s protocol software,
you must define the DLI sessions and the transport subsystem interface (TSI) connec-
tions between your client application and Freeway (or an embedded ICP). To accom-
plish this, you first define the configuration parameters in DLI and TSI ASCII
configuration files, and then you run two preprocessor programs,
dlicfg and tsicfg, to
create binary configuration files (see Appendix B). The
dlInit function uses the binary
configuration files to initialize the DLI environment.
