Hi Gilles. I don't think it's a security problem. Make sure, if you are using /etc/yasr/yasr.conf, that the doubletalk line and the serial port line are the only ones you have uncommented. it may be that the yasr.conf came with certain lines already uncommented by default. Also, I'm assuming that your doubletalk actually is at /dev/ttyS0. Finally, I've found that sometimes when I've made a change or reinstalled either the source package from the yasr homepage or the debian yasr, sometimes i have to log out and back in again for it to work. I'm just making guesses; hope this helps. right now I'm using it primarily with eflite but i have had it working with the external doubletalk. -- Cheryl "Where your treasure is, there will your heart be also." _______________________________________________ Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
