TR3271 Management Programming Manual

COMMANDS AND RESPONSES
STOP Command
STOP Command
The STOP command terminates the operation of the specified
object. You can stop a line or a subdevice, but not a
process. When the subsystem completes processing the command,
the specified object is placed in the STOPPED summary state.
When you are using the STOP command, the termination is done in
a more orderly fashion than the ABORT command. The subsystem
checks for subdevices currently open before terminating the
connection. If there are subdevices open or there is an AM3270
subdevice connected to a TR3271 subdevice, the subsystem rejects
the command and returns an error.
This command cannot be issued when the line is in the STARTED
summary state with subdevices open or connected, or when the line
is in the DIAGNOSING state.
When your management application issues the STOP command for a
line, the subsystem checks for the optional subordinate-modifier
token. If the value of the modifier is ZCOM-VAL-SUB-ONLY, the
subsystem stops only the subdevices attached to the specified
line. If the value of the modifier is ZCOM-VAL-SUB-ALL, the
subsystem stops the subdevices first, then the line. If the
value ZCOM-VAL-SUB-NONE is specified, the subsystem checks that
there are no subdevices in the STARTED summary state, and then
stops the line.
Once the line is stopped, processing cannot continue until the
line is started again.
When your management application issues the STOP command for a
subdevice, the subsystem stops only the named subdevice. Your
management application can specify the SUB modifier with the
value ZCOM-VAL-SUB-NONE or ZCOM-VAL-SUB-ALL. This value causes
the subsystem to stop the named subdevice. The line must be in
the STARTED state. If the value ZCOM-VAL-SUB-ONLY is specified,
the TR3271 subsystem returns an error.
