Re: what is a mailslot?

The mailslot in the left magazine is used only with host system software that supports this feature. The
mailslot feature allows you to insert or remove a single tape without removing the entire magazine. The
benefit of using a mailslot is that the Autoloader will not inventory the rest of the slots in the magazine so
the device can return to service sooner. The mailslot is in the left magazine.
