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.
