I used the voltmeter on LPT port a lot lately!
In early CT versions, just pin 1 was enough for TTL keying as it used
natural STROBE function going low when activated.
TR decided to key pin 16 with a positive signal. Universal keying circuit
needed NPN transistor for compatibility between both programs.
It claimed 50 mA keying capability which is way bellow pin 1 sink ratings.
ARRL handbook announced a circuit which used pin 1 as enable for PTT. It
used plenty of relays for various switching.
Writelog was keying both pins 1 and 16 affecting smooth PTT operation in
commercial SO2R boxes.
Free N1MMLogger didn't do that with pin 1.
Now we develop SO2R situation with pin 1 permanently low, pin 14 going low
for Radio B and no power source for my miniature LPT adapter :-(
May I kindly ask for a pin 1 to go low at PTT time and everything will work
fine in USA and EU!

in case anyone would really like to know what happened here...
Over the past 12 months or so a couple of folks reported that WL did not
handle pin 16 correctly.
I checked everything thoroughly and never found a problem in my shack.
This month, one kind sole actually put a voltmeter to his LPT port before
sending out emails about pin 16.
His report was that WriteLog was handling pin 1 differently than "everyone
else" (NA/CT/TR).
WL 10.29 changes WL's behavior on pin 1 (NOT PIN 16!).

I installed 10.69 last night and now my WX0B SO2R box works as
advertised. No more CW on Pin 16. Perhaps we will never know why it
happened, but I am a happy camper now.
