Queries
<QRY> <My Socket> < >
or <QRY> <Your Socket> <Text>
Queries provide an extension to the <ERR> facility as well as limited error recovery, thus avoiding re-initialization of an NCP.
The first command requests the remote NCP to supply the status of all connections to the user specified by the user number in <My socket>. The second is the reply; <Text> contains the connection status information. If an NCP wants the status of all connections to a remote HOST, the <My Socket> is zero.
