WL version 10.28 and earlier drive pins 1 and 17 on the LPT port with
the CW signal. Pin 1 goes low for key down, and pin 17 goes high for
key down.
Version 10.29 changed to hold pin 1 low all the time.
Version 10.30 added an INI entry
[ports]
cw_on_pin1=1
If you add this INI entry, it signals CW on pin like 10.28 and before.
