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
Good luck!
