BSC Loopback Test

Note

In this chapter, the DLI API interface applies to both a Freeway

server or an embedded ICP using DLITE. For the embedded ICP,

also refer to the user’s guide for your ICP and operating system (for

example, the ICP2432 User’s Guide for Windows NT (DLITE Inter-

face)).

E.1 Loopback Test Programs

The BSC loopback test programs and test directories are listed in Tab le E– 1 and

Ta ble E– 2, according to operating system (UNIX, VMS, or Windows NT). This section

provides a summary of the steps required to run the loopback test; see the Loopback Test

Procedures document for the details and an example output (this information was pre-

viously in the Freeway Server User’s Guide). The loopback program uses non-blocking

I/O, meaning that the

asyncIO DLI configuration parameter (described in the Freeway

Data Link Interface Reference Guide) must be set to “yes” (the default is “no” for block-

ing I/O).
