2.Buffered writes are used to allow time for additional data to be transferred, thus keeping the tape streaming. If non- buffered, controller returns status only after all data has been written to the tape. If buffered, controller returns a good status when all data has been transferred to the buffer, although all data may not yet have been written to the tape.

Inquiry Packet
The inquiry command ($12) returns information from the controller that identifies which controller is attached and its attributes. The format and the number of bytes returned varies from controller to controller (refer to the appropriate controller manual for this information).
The returned data is put in the specified address, and the length does not exceed the data length provided; however, the actual length and content information returned depends upon the controller.
The first table below shows the inquiry packet. The second table shows the inquiry data return packet.
