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.
