BUEP03E Protocol 8-11
8.7.2 Operating Method
The BÜP03E protocol provides the user with a number of commands.
These commands then execute the jobs which are required for communi-
cation.
The following commands have been defined:
- Start
- Receive
- Transmit
- Reset Receive Buffer
- Data Copy
- Formatted Output
- Receive Mode
- Terminate Job
Each command is indicated by a job parameter list. All these commands
are activated by the R5REQ. The Terminate Job command is provided by
the R500 system. The remaining commands form the BÜP03E protocol.
In order to be able to activate a peripheral, the user has to execute many
of these elementary commands via a function call module. This is a major
problem from the point of view of time and management. It would be ea-
sier to link several elementary commands toghether, and start them via a
function call module. This method of combining commands is explained
on Page 8-12.
