Hi,

i want to use [http://rubyforge.org/projects/ruby-serialport/](http://rubyforge.org/projects/ruby-serialport/) to  
communicate  
with /dev/ttyS0 (com1). Has anyone experience with this library or  
perhaps  
an example code?

Cheers,  
Stefan

I actually used EventMachine and the Ruby-Serialport project you  
reference to do it:

[http://rubyforge.org/pipermail/eventmachine-talk/2008-January/001567.html](http://rubyforge.org/pipermail/eventmachine-talk/2008-January/001567.html)

The code snippet in that link only works with Eventmachine 0.10.x. I  
think the core changed in later versions. Using that code snippet, you  
can do event-driven programming on a serial port the way one would  
program a network client in EventMachine.
