          before loading the driver.  NOTE: If you have not already done so, you will

          Device Server/Terminal Server and configure this before the driver will be able to   
          see the device. See the manual for further instructions.   If you have already Digi 
          configured the Digi Device Server/Terminal Server, enter the IP Address           
          here. NOTE: Leave the TCP port set to 771
