Note
In this document, the term “Freeway” can mean either a Freeway
server or an embedded ICP. 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).
C.1 Loopback Test Programs (nrmalp and nrmtest)
The ADCCP NRM loopback test programs and test directories are listed in Ta bl e C –1 ,
according to operating system (UNIX, VMS, or Windows NT). The nrmalp program
prompts for a single port pair (0/1, 2/3, 4/5, or 6/7), whereas nrmtest prompts for a
series of such pairs. Both run in DLI Normal mode. This section provides a summary of
the steps required to build and start a loopback test; see the Loopback Test Procedures
document for the details pertaining to nrmalp, and an example output from it (this
information was previously in the Freeway 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 blocking I/O).
The nrmtest program and makefiles are not delivered for VMS, although the nrmtest.c
program may be built under VMS if the necessary makefiles are created by reference to
existing makefiles.
