Hello,
i'm using boost asio 1.66 serial port on a Ubuntu Mate 64 machine, and I
facing the fact that open("port name", error_code) command on an already
openned port do not return an error.
Could you please check the previous release of Boost?

For example, in my case, version 1.65.1 used on  CentOS Linux release
7.4.1708 (Core).

If ttyS0 opened with screen (screen /dev/ttyS0 115200) ASIO will not
open it with error

$ sreqrep /dev/ttyS0 "%%"
[2018-01-11 17:49:30.868] [serial] [error] Error: Device or resource busy
$

If your case related only to 1.66, then it'll be possible regression bug.
