Emulating a DCE

Am I overlooking something obvious? I have an application where the Digi Connect ME will be acting as a modem to a serial terminal. I don’t see any examples that set up the I/O ports for this configuration. The intent is that DCD will follow the socket status: turn on when the socket is established and turn off when it disconnects. RTS and CTS will then be used as bidirectional Clear To Send signals for full duplex operation. It seems like a rather obvious application. Did I miss it, or is it missing? Thank you, Bob McConnell
