The majority of the work processed by the TPF system originates from
terminals, workstations, or other systems, all of which are connected through
communication networks.
The major functions of communications control within the TPF system
are:
- Handling of different communications protocols
- Identification of message source
- Formatting of messages (input and output) based on requirements imposed by
application type and terminal or workstation type
- Controlling the flow of message traffic between a central processing
complex (CPC) and communication facilities based on the volume of messages
- Error recovery.
