Hi Wayne, After reading again the page below ................I tried out several things with the latest version of WL and up to date W2K I have a dualboot with Win98se and W2k (installed on different Disks) and the PTT function via LPT is working great, am I lucky or maybe they changed there drivers again in the latest patch same counts for DX4WIN also no problems found with the LPT-PTT btw My LPT ports are installed like normal ports no EPP- IRQ etc .
