I installed CT Win and tried to use CW keying from two different IBM thinkpad 
laptops. I built a NPN keying circuit using pins 1, 17, and 18 along with a 1K 
resistor. I can hear CW being generated by CT from the computer with SOUND on 
but there is no fluxuation coming out of the pins of the LPT1 connector. I 
tried it on another IBM thinkpad 600 and the same result, I could not key the 
rig as there was no CW coming out of the LPT port.
Any ideas what I am doing wrong or is there some parameter in the IBM thinkpads 
that need to be changed to allow CW keying. I would appreciate any help.
