[ros-users] Serial Port Problems

[Daniel Stonier]

We were reinventing this wheel too often, so wrote some standard
device classes customised for control (this kind of thing). If you
want to grab the serial class files, or use the repo, you're welcome
to it.

(serial_pos.hpp and serial_pos.cpp should be simple to convert to
whatever you need).

I didn't know you could lock them, that was a nice piece of
information from this, cheers!
