your best bet in this case is to connect your device via USB to your PC and connect to OpenDingux using telnet. Then you'll have a full blown bash terminal, and you can run applications from there and see their output on the terminal.
Of course, for that you'll need to know how to navigate a bash terminal - some Linux background is helpful in this case. Also, you'll only be able to connect to OD via telnet from a Linux PC or MacOSX. The Windows drivers for USB ethernet don't work correctly for this.
The IP address for the device when the USB link is correctly setup is 10.1.0.2
