Happy to hear that it works for you!
Which distro are you using it with? (Just curious...)

@agkbill:
A new version of serial-pyio has been released on July 1st. If you're still using the old v0.1.1 (commandline), it's all new and shiny with a GUI:

...and if you have any problems or encounter bugs, please let Julien or me know.
