How to get terminal app data to a GUI app

[cmk1523]

So I created a nice serial/UART program and it runs very well through "mobileterminal".

I tried running the same code using a GUI hello world example, however it doesn't output anything to my connected UART device so I'm assumming it doesn't run or there is permission issue opening the serial port via the commmand...

open("/dev/tty.iap", O_RDWR | O_NOCTTY | O_NONBLOCK);

My goal is to get UART data to and from a GUI.

I'm about to tear apart the "mobileterminal" app source code to see what I can do. I'm just wondering if it has been done?

Maybe try contacting some of the developers of mobileterminal - Google Code and see how they addressed the front end GUI permission issues. Like I said on your UART thread, I'm very interested in this, it's just quickly escaping my field of expertise.
