Thanks for the info, Brian and Geoff. At least that clears things up 
that the driver should not work over serial out of the box. Although we 
did have it working at some point (pre 1.0), but I guess we were just 
lucky that some other tool set the right baudrate and everything for the 
serial device before we started hokuyo_node.

I'll give it a try! Is that ROS node planned anytime soon? The best 
(long term) thing would be to have serial support in the main 
hokuyo_node. I'll let you know when I figure out the right commands, it 
shouldn't be too much as we already had it working over serial in some 
configuration.

Cheers,
Armin
