REJECTING MESSAGES FROM CERTAIN SENDERS
Programming the List of Senders for Authorized Reception
A terminal sending an incoming message always identifies itself to your
machine. The identification consists of an RTI or CSI. Before you can use
Authorized Reception, you must program a list of senders you wish to treat
differently. These senders and their RTI's/CSI's are known as Special
Senders. Use function 71 to enter this information(see the next page).
