Hi everybody, i am new in this forum and this is my first post. "I know many of you know these concepts, but only to be clear" UART: serial port in the dock connector GUI: Graphical user interface I want to made an application for the ipod touch, and this application must made a bidirectional communication using the UART. The problem is, i want use the graphical interfaces not a tty (shell). I know i can use the UART port, i use minocom to check this, and i made a program in C to send data using the UART, but i am very loss in the GUI UIKit library. So the question is, there is a component to made this communication between C and UIKit or a library that include the control of UART for the GUI. So fellows sorry for my English is not my mother tongue, and I have the hope that some body can help me with this questions.
