[ct-user] two radio switch????!

[NOEL POULIN]

Hi all
Am trying to switch  cw keying on CTWIN  by the ALTERNATE.
Before installing the relay on pin14 of LPT1, am just monitoring the voltage on this pin 14...it is 5v.....
When I switch CTWIN from one radio to radio 2...by the command alternate., there is always 5 v on this pin 14.....
What am I missing ..Is this pin 14 supposed to be in low(no voltage) when I switch from one radio to another????
I would appreciate your help very  much.
Thanks\
