3.2.5.6 DPSP_MSG_ADDFORWARDACK
When a DirectPlay host computer receives a DPSP_MSG_ADDFORWARDACK message (section 2.2.9), if the host has an outstanding DPSP_MSG_ADDFORWARDACK from the client which sent the message, the DirectPlay host computer MUST indicate that it has received the DPSP_MSG_ADDFORWARDACK. When the DirectPlay host computer has received a DPSP_MSG_ADDFORWARDACK message from all of the clients to which it sent the DPSP_MSG_ADDFORWARD message (section 2.2.8), then the game host MUST format and transmit a DPSP_MSG_SUPERENUMPLAYERSREPLY message (section 2.2.53) to the client that sent the DPSP_MSG_ADDFORWARDREQUEST (section 3.2.5.5).
