We report on software developed in support of the Fermilab FASTBUS Smart Crate Controller. This software includes a full suite of diagnostics, support for FASTBUS Standard Routines, and extended software to allow communication over the RS-232 and Ethernet ports. The communication software supports remote procedure call execution from a host VAX or Unix system. The software supported on the FSCC forms part of the PAN-DA software system which supports the functions of front end readout controllers and event builders in multiprocessor, multilevel, distributed data acquisition systems.
