[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
