Say Enter "RTL readlen=524288" in the 'ExtIO : Device hint' edit field, when that is what you mean

OK I get it. I wish those who write this stuff were not so Cryptic and Acronymous. On this page ... http://wiki.spench.net/wiki/USRP_Interfaces the author has an entry that looks like this "RTL readlen=524288" yet nowhere in the immediate text is there any language stating to enter this text in the 'ExtIO : Device hint' edit field, you have to sort of guess the author thoughts. No one is ever thinking like the one who is doing the original thinking so to reproduce original thinking adequate references to what the author is thinking is required to reproduce the original thoughts in the reader's mind. Literate illustration makes everything so much easier (and a liberal sprinkling screen shots). Thanks Jay Salsburg
