National Instruments provides a C language interface to its driver on most platforms in a file called cib.c. For some older versions of the National Instruments driver, spec has built-in C code that can be used instead of the National Instruments C interface. When using the National Instruments cib.o file, it isn't possible for GPIB devices that generate service requests (SRQ) to generate interrupts. Such devices must be used in polled mode.

In addition to specifying this choice in the config file, the location of the cib.o file must be entered when spec is installed. See: SPEC Administrator's Guide. Any of the National Instruments boards (except the DEC MicroVax board) can be used with the cib.o file.
