I've read through the walkthrough on using the serial port but I am still having trouble communicating. The device communicates via DNP3 protocol over RS232 and works fine when connected to other serial ports. Here's the setup...
[Device] -> [serial0 -> RB450G -> remote access -> rfc2217] -> network -> [Virtual Serial Port Emulator -> TcpClient -> Connector] -> COM5 -> Software
The funny thing is, I get about four seconds of good communications after I cycle power. After that, no more successful communication.
Could there be anything different about the serial port on a RouterBoard (I've also tried and had the same results on an RB433AH) than the standard? Any suggestions for debugging?
