+@item most of the extended protocol (diagnostic/file/pipe/setting/information)
+@item TCP, UDP, Serial ASCII, Serial RTU, and Serial Binary
+@item asynchronous and synchronous versions
+@item payload builder/decoder utilities
+@item pymodbus read eval print loop (REPL).

+It also includes the following @emph{server} features:
+@itemize
+@item can function as a fully implemented Modbus server
+@item TCP, UDP, Serial ASCII, Serial RTU, and Serial Binary
+@item asynchronous and synchronous versions
+@item full server control context (device information, counters, etc)
+@item a number of backing contexts (database, redis, sqlite, a slave device).
