Application programs are informed by the deallocate indicator (RPL6WDAL) in the What-Received field of an APPCCMD CONTROL=RECEIVE macroinstruction that the partner application has begun deallocation of the conversation. The conversation is then placed in SEND_ONLY state. The application program can continue to send information. When all information has been sent, the application program issues an APPCCMD CONTROL=DEALLOC, QUALIFY=FLUSH|DATAFLU. This ends the full-duplex conversation and the conversation enters FDX_RESET state.
