operationRegister = status.operation.remote.condition
operationRegister = status.operation.remote.enable
operationRegister = status.operation.remote.event
operationRegister = status.operation.remote.ntr
operationRegister = status.operation.remote.ptr
status.operation.remote.enable = operationRegister
status.operation.remote.ntr = operationRegister
status.operation.remote.ptr = operationRegister
operationRegister
Details
These attributes are used to read or write to the operation status remote summary registers. Reading a status
register returns a value. The binary equivalent of the returned value indicates which register bits are set. The
least significant bit of the binary number is Bit B0, and the most significant bit is Bit B15.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
2) and Enable and transition registers
meanings:
Bit Value
B0 Not used
B1
status.operation.remote.COMMAND_AVAILABLE
status.operation.remote.CAV
B2-B10 Not used
B11
status.operation.remote.PROMPTS_ENABLED
status.operation.remote.PRMPT
B12-B15 Not used
As an example, to set bit B1of the operation status remote summary enable register, set
status.operation.remote.enable = status.operation.remote.CAV.
In addition to the above constants, operationRegister can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set operationRegister to the sum of their decimal weights. For
example, to set bits B1 and B11, set operationRegister to 2050 (which is the sum of 2 + 2048).
Example
status.operation.remote.enable =
status.operation.remote.CAV

The operation status remote summary register's status. A zero (0) indicates no bits
set (also send 0 to clear all bits); other values indicate various bit settings
(on page E-18). The individual bits of this register have the following
