This section describes the language used and the actions taken by a terminal operator in order to gain access to the environment (application programs and system facilities) controlled by the Message Routing Facility.
Input from any terminal not permanently logged in and not classified as the
PRIME CRAS (PRC):
LOGI xxxx |
Where:
Explanation: The terminal operator requests to be connected to the application referenced in the message.
Normal Response: LOGI COMPLETE
The connection has been accomplished.
Error Response:
The format of the input message is in error.
The name of the requested application does not appear in the RCAT.
The application is currently not active (stopped).
LOGO |
Explanation: The terminal operator requests to be disconnected from the application currently logged to.
Normal Response: LOGO COMPLETE
The terminal has been disconnected and it is idle. A log-in message may now be entered.
Error Response: NOT LOGGED TO APPL
The terminal is not currently logged in.
A message of the type defined LOG IN can be entered from a non-SNA terminal to concurrently log off and log in to an application. Normal and error responses, as specified for the above messages, apply to the combination messages.
In order to input a command from a terminal, the terminal user must first log in to the System Message Processor. The application name specified in the log-in message must be SMPx, where x is the CPU ID of the TPF system to which the terminal operator intends to send the commands.
As already described, the PRC terminal is always logged in to its own SMP.
Terminal actions required to send or receive an unsolicited message are described in DCSR-UMP.
