[WT-support] SO2R and parallel port

[Franta Bendl]

Hi Pablo,

thank you for the reply.

I can't believe that the LPT is demaged, because

1. I have here 2 Laptops with identical behaviour
2. there is a change of the status on pin 14 but at the wrong moment

OK, what is the situation - checked with voltmeter and there is nothing 
connected to LPT (+5V = high, 0V = low):

1. start of WT (R1), pin 14 = high
2. F1, start CQ, pin 14 = high
3. end of CQ, pin 14 = high
4. switch to R2, pin 14 = high
5. F1, start CQ, pin 14 = low
6. end of CQ, pin 14 = high
7. +, TU, pin 14 = low
8. end of TU, pin 14 = high
9. switch to R1, pin 14 = high

I.e. the pin 14 works, but only as "AND" of "Active Radio" and "PTT".

If there is other behaviour at your system, please send me your WT 
configuration of the LPT, maybe there is the difference. At my system I 
have

Port 378
DVK - On
Extended DVK - On
DVK/Stop - Off
Band data - Off
Active Radio - On
Stereo RX audio - On (Pin 9)
Headphones Control - On
CW and PTT - On
