+     <p>DSRemote is a program to control and visualize your Rigol® DS6000 or DS1000Z series oscilloscope from
+your Linux desktop via USB or LAN. It will probably work as well with the other series like DS2000A and DS4000 series but
+I have no access to all those oscilloscopes so I can not test it</p>
