of the device, the message shows on your screen for the time set in the Maximum Wait drop-down list.

Receiving a message

When a computer sends a message to the computer controlling the device, the message displays on the

monitor of the controlling computer for the time specified by the Time-out value.

The message box has two buttons used to respond to the message. When you receive a message, enter a

response in the message box and click on one of the following buttons.

 Yes: Click on Yes to give up ownership/control over the network device.

The computer automatically disconnects from the network connection, and control over the device

transfers to the computer that sent the message. The Device Owner property in InstaCal updates with the

name of the computer that gained control of the device.

 No: Click on No when you do not agree to give up ownership or control over the network device.

When you click on a button, the message box and selected response displays on the computer that sent the

message.
