Subject: Support MAC OS X 10.7,10.8
X-Git-Tag: submit/trunk/20190927.044709~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d6f6bfeae18d7359a972c75e95b80d5e5352576c;p=tools%2Flthor.git

Support MAC OS X 10.7,10.8

On OS X the serial device must be opened with O_NONBLOCK flag.
Later this flag must be cleared before write operations otherwise
only small chunks data can be written at once.
Tested on OS X (10.8.4).
