ePub | Page 566 multiple code examples |
In the section on "The at Command", in the epub version seems to be missing the actual "at" command in the examples. It's a bit hard to describe in pure text, but I've posted an annotated picture at https://twitter.com/gumnos/status/850835233847037953 that shows the commands where one would expect to see "at". I suspect this is either a layout/typography issue or errant search/replace that took. In case it matters, this is on a Nook Simple Touch (an e-ink device). |
