Receive Ready Notification
If the host on the receiving side cannot receive files for some reason (such as when the HULFT system on the host has been temporarily disabled), the host on the sending side can be notified when the receiving host has recovered and is able to receive a transmission. This function is called 'Receive Ready Notification.'
You can enable the Receive Ready Notification by running a command. Notifications are sent to all the hosts that are registered in the Host Information.
