Description
The power has been turned on.
Local control is requested.
This bit is set irrespective of the remote/local state of the device.
Since this bit is not supported by MS9710C, it is always 0.
A program message including a syntax error or a misspelled command
has been received or a GET command has been received in a program
message.
A program message which is syntactically correct but cannot be exe-
cuted has been received.
An error other than CME, EXE, and QYE has occurred.
An attempt was made to read data from the output queue while it has
no data, or the data in the output queue has been lost due to overflow,
etc.
The device is required to be an active controller. Since this bit is not
used by MS9710C, it is always 0.
The device has completed the specified pending operation and ready
for receiving a new instruction.
This bit responds only to the ∗OPC command and sets the operation
complete bit.
