Even if I open the tty device with O_NOWAIT option, the read operation is still blocking. ie read(tty, pBuff, 1) returns only after at least one character has been sent to the yaroze. In my point of view, this is a key point for multiplayer game implementation as you need to test for incoming bytes without blocking the program execution. 2) what is the O_NOBUFF option of open? 3) Is ioctl documented somewhere (or source code example available). How to change baud rate, settings etc.. sceetech maybe? Sorry for my english Jean-Luc
