As an example, to set bit B0 of the operation status LAN summary enable register, set
status.operation.instrument.lan.enable = status.operation.instrument.lan.CON.
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 B10, set operationRegister to 1,026 (which is the sum of 2 + 1024).
