[SD-User] CW using LPT on XP System

[Kevin Martin]

Hi Paul

I have made a LPT Interface to generate CW from SD. All that happens 
when I trigger a CW Message is a constant tone. I have to restart the 
computer to stop the tone. I am using Windows XP Home with SP2. The 
interface was built using the design in the SD Manual. Any Ideas?
Regards
