Description

A pibs item is required for each process executing on the system.

The items in the pibs file define the memory resident hooks of the process workspaces. The pibs file also defines the physical devices connected to the system’s ports, such as terminals, printers, phantoms, or communication ports. The port numbers are the item-IDs.

Device control information is derived from the pibs file and the devices file. The pibs item specifies the device type and the devices item defines device characteristics and drive functions.
