I am using Modbus Poll to connect thru the smg-5420 to a modbus rtu rs485 device. This setup works OK when Modbus Poll is connected to the smg-5420 server. When I try to use a ezVSP virtual com port, I can not communicate with the modbus device. I see that when I use Modbus Poll in Modbus/tcp that the tcp header gets sent with the serial data to the smg-5420 server. With Modbus Poll thru the serial port only the serial data gets sent to the smg-5420 there is no tcp header information. Is there some setting I need for the ezVSP virtual com port to add the tcp header? Thanks, Dan
