Hi Again Dmitry

This is a very interesting post. I new about GNAT.Serial_Communications but I hadn't looked at the sources in a while. I wasn't really impressed when I read it the first time but I am now.

It binds to fcntl and it opens with O_NDELAY, which is similar to O_NONBLOCK.

There is a post here about the difference:
https://mail.python.org/pipermail/python-list/1999-May/013687.html

This serial package also gives code examples that could be used with any device to avoid blocking.

Thanks again! -Patrick
