Hi Tommy. As of Friday aug. 15, the Litetalk / doubletalk-lt driver seems to be broken. I get a LiteTalk not identified error message. By the way, the proper way to set up the synth after booting is: setserial /dev/ttySx uart none echo ltlk >/proc/speakup/synth_name This allows the need to load the driver with modprobe. This may have been changed, but in the past, modprobe didn't load the modules properly. Kirk and I are looking into why the driver doesn't identify the doubletalk-lt properly. It was working and somehow got broke. Gene
