I am using Sun Java 1.4 and I am using the rxtx
package, exactly the one described in the above link.

The problem is things work fine with /dev/ttyS0 but
gives problem with /dev/ttyR0(one of the multiport
serial port). 

The code also have a function as follows to find all
the available ports. This function prints only
/dev/ttyS0 and /dev/lp0 as the available ports 

   public void PrintAllPorts( )
    {
        Enumeration ports =
CommPortIdentifier.getPortIdentifiers();

        if (ports == null) {
          sf.VERBOSE("No comm ports found!" );
          return;
        }

        // print out all ports
        sf.VERBOSE( "printing all ports..." );
        while ( ports.hasMoreElements() )
        {
          sf.VERBOSE( "-  " +
((CommPortIdentifier)ports.nextElement()).getName() );
        }
    }


Thanks
Sumit
