+The @value{GDBN} remote serial protocol includes @dfn{reportasync},
+packets that the stub can report status or do an operation in any time.
+If the stub supports @dfn{reportasync}, it should report that to
+@value{GDBN} by including @samp{ReportAsync+} in its @samp{qSupported}
+response (@pxref{qSupported}).
+
+When the stub want send @dfn{reportasync} packets, it send shake hands
+packet @samp{^} to @value{GDBN}.
+If @value{GDBN} reply a @samp{^}, the shake hands is successful.
+If not, the shake hands is fail and this packet need to be handle
+as a simple packet.
+
+After shake hands, the stub can send packet to @value{GDBN}, the packet
+format is same with simple remote serial protocol.
