Don't meen to be rude here, so if you don't know what xterm is you must google it and read up on it and then come back and install NITdroid. You need to understand the basics of xterm to use it for anything like this

On a side note really funny how these new NITdroid threads turns in to help threads and how people just keep asking the same questions instead of spending a little time on reading/searching through the thread(s). Further more not using the dedicated forum for all stuff regarding NITdroid
