[quoted lines by Greg KH on 2014/08/30 at 17:01 -0700] >What does strace say? Good suggestion - thanks. I should've tried that in the first place, and am sorry for having bothered you. In fact, both POLLHUP and POLLERR were being set, but the code was losing that fact. The code actually did resume executing, and eventually did a read() which didn't fail. What's special about the read is that it's done with the serial device in non-canoical mode so it was returning 0 (rather than -1), and, thereby, not signalling that there was a problem. I'm not sure if, in this type of case, the non-canonical read should perhaps be returning -1 with errno set appropriately. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
