If you start java -jar remotekvm.jar it prints:

Missing parameter!
Usage : <path to java.exe> -jar <RC application jar> [command line options]

The options are defined as follows:
-host     the host IP/name of the AMM to connect
-nsport   the network service port of the AMM to connect, default value is 3900.
-rbs      the rbs handler for authentication
-b        the slot number of the default blade to access
-disable_blade_switch
          the blade switching flag, optional, default is enabled.
          and remote drive switch on the Remote Console Applet will be disabled too.
-disable_remote_media
          the remote media flag, default is enabled.
-mntpoint the default mount point of a remote media. This option will be ignored if
          remote media is not enabled. Optional.

This is misleading! The correct parameters are:
-s = host (string)
-n = port (int)
-b = defaultBlade (int)
-mc = mpCount/mountPointCount (int)
-d = mountPoint (string)
-B = disableBladeSwitch (true/false)
-R = disableRemoteMedia (true/false)
-r = rbs (int)
-c = climode (true/false)
-libpath (string)
-cp = commPort (int)
-showui (true/false)

Defaults:

RBS    : 0
Host   : null
Port   : 3900
Default: 0
DisSwch: false
DisRM  : false
MntPT Count:0
LibPath :null
