Echo Reply

If an Echo Request control message is received from the remote application, the message handler constructs an appropriate Echo Reply control message as described in Section and writes it to the Control Message Interface file descriptor in the outbound file descriptor list.

Start File Transfer

If a Start File control message is received from the remote application, the message handler opens a new file descriptor using the file's context information contained in the control message and appends the file descriptor to the inbound file descriptors list.

End File Transfer

If an End File control message is received from the remote application, the message handler closes the file descriptor for the file transfer indicated and removes it from the inbound file descriptors list.
