I just started porting over some Python applications that we had running under the Digi Connect 3G IA device that use MODBUS. When I started setting up the MODBUS configuration in the Digi Transport WR21, I noticed that if I look at the Management - Connections > IP Connections, I don't see port 502 listening, even though the MODBUS configuration I'm using says to use that port. Has anybody been able to get MODBUS TCP-Serial working on this device? Thanks
