Using serial port with opengl

Posted 11-17-2008 at 06:58 AM by nasr-noor
Hi all,
I use glut library and read from serial port in my program.
when I read a special frame from serial port, I redisplay the window with glutPostRedisplay().But it doesn't work and glutPostRedisplay didn't has any effect on my window.
note: I use thread for reading serial port.
thanks.
