Thank you for your interest of SMG-5420 and ezVSP.
Currently, ezVSP does not ship the modbus gateway function like a SMG-5420.
We welcome customers comments and suggestions.
If we continue to receive customer requirements for that function, we will consider applying them.

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?
