Hi John,
No problems. It is a very simple serial comms app that I use as an alternative to the Arduino IDE when I want to do such things as pass arduino data to Mac/WIN7 Applications. I am pondering a recast while I interface a 16key touchpad to a theatre app for sound and video control. If you wish, I can easily send you the simple RealStudio .rpb file to play with. There is a minor difference between the device ID's on Mac USB-Serial driver and the WIN7, but it works fine cross-compiled for both. (Haven't run it up on a Linux box yet - that would be interesting too).
One capricious app for this was a midi interface emulating a drum kit using piezo-sensors. Learnt a lot, but it's a totally useless application.
I do plan to interface my arduino data-logger to a graphical interface, but I have not yet drafted interrupt-driven change-detection arduino code that I like and I don't want to go with polled collection.
