Abstract
A module for executing SCSI commands. The module includes a computer process, and communicates with a SCSI bus, which carries SCSI commands. Ordinarily, the SCSI commands cause specific actions in SCSI devices: for example, a given SCSI command may cause a SCSI printer to eject a sheet of paper. The module also responds to the SCSI commands, but in a manner determined by its programming, and not necessarily consistent with SCSI conventions. For example, the module may respond to the command just identified by looking up the time-of-day, and presenting the time-of-day to the SCSI bus, for any interested parties to observe.
