FreeBSD?

This is with Chromium 45.0.2454.93 on FreeBSD 10.2-RELEASE #0 r286666

Running unpacked from github. I'm guessing it's FreeBSD not seeing the serial ports.

Which are:
crw-rw---- 1 root wheel 0xa3 28 Sep 01:06 /dev/ttyU0
crw-rw---- 1 root wheel 0xa4 28 Sep 01:06 /dev/ttyU0.init
crw-rw---- 1 root wheel 0xa5 28 Sep 01:06 /dev/ttyU0.lock
crw-rw---- 1 uucp dialer 0xa6 28 Sep 01:06 /dev/cuaU0
crw-rw---- 1 uucp dialer 0xa7 28 Sep 01:06 /dev/cuaU0.init
crw-rw---- 1 uucp dialer 0xa8 28 Sep 01:06 /dev/cuaU0.lock

I'm in wheel and dialer but I'm guessing this is either compiled without serial support or just doesn't know which files to look at. I'll take another look shortly.
