+	bool "nanocom"
+	help
+	  Nanocom is based upon microcom (http://microcom.port5.com/)
+	  but removes the scripting and logging features while
+	  introducing support for setting local/remote echo, parity
+	  and stop bits. It also follows a more standard command line
+	  style using the getopt function.  Internally much of the
+	  code has been rewritten and reformatted, the menu system in
+	  particular is almost entirely different.
