[ros-dev] serial port type detection (pt. 2)

[Mark Junker]

Hi,
in a documentation I saw that I probably had a bug in the patch for the
serial port type detection. The attached patch should fix the problem.
This comment in this patch also explains what is/was my problem with the
value(s) specified in the documentation.
Regards,
Mark
