timeout
The maximum waiting time (in milliseconds) until the response is received from the device. WaitForever can be specified.

The targeted cancellation operation is identified by the settlement number that is contained in the ApprovalCode property.

When timeout is WaitForever, time-out never occurs, and it waits indefinitely until it receives a response from the device.

This method is performed synchronously if AsyncMode is false, and asynchronously if AsyncMode is true.
