idspcli.jse
    syntax: sewin32.exe idspcli.jse [host] [port]
     where: host - the Internet address (IP/URL/Computer name) of the
            computer running an iDSP server script. Default is "localhost".
            port - Port to which to listen for internet connection.
            Default is DEFAULT_IDSP_PORT (defined as 1066 in idsp.jsh).
      desc: This script starts a connection with a computer that is running
            an iDSP server script. The connection is accomplished using
            Internet protocol. The purpose of the connection is to run
            ScriptEase commands on the host/server computer by means of
            distributed scripting.

            This script is simple and sends several simple statements to be
            executed on the server computer.
   example:    // Start idsp client on default port 1066
            sewin32.exe idspcli.jse
               // Start idsp client, specifying the default port
            secon32.exe idspcli.jse 1066
               // Start idsp client, specifying another port. If the default
               // is not used, then the server script must specify the
               // same port.
            secon32.exe idspcli.jse 1011
