Medoc over Ethernet to E-terminal to Mitsubishi CPU

Is anyone out there having success with using Medoc over Ethernet (by using COM/IP or any other COMM-to-TCP redirection software) to download/upload/monitor PLC programs of a PLC connected to a Ethernet enabled E-terminal with transparent mode. I have COM/IP working with hyperterminal but medoc still gives communication error when I try to go online with the Mitsubishi CPU.

thanks,

Seth
