Rik,
I switched to the serial port and of course rewired the connector and
changed the interface to a PNP transistor. All is fine and well now. It has
been running all weekend without any trouble. There is a minor bug in your
QRS3.17 in Windows 3.11, but I'll report about that later today for you.

Subject: Re: LF: LPT/Parallel port setup for transmitting???
Hello Bill,
QRS should work fine with the parallel port if running under Win3, Win95
and Win98. The way I acces the parallel port will not work under WinNT,
Win2000, WinXP as these operating systems do not allow direct acces to the
memory locations I use to handle the LPT port. (it seems to be a hobby of
mr. Gates to make life hard for those who want access the hardware of a PC)
The fact that accessing the LPT port via DOS also failed makes me
suspicious that you could have a defective LPT port. Or you are trying to
access the wrong port, if LPT1 doesn't work give it a try with LPT2.

I am using Windows 3.11 with the QRS 3.17 program and keyer design that
comes with the program. I am keying an Epson Oscillator with a 10k resistor
in series with the collector of the NPN transistor. I am using pin 2 of the
LPT port. Pins 18 thru 25 are tied together and to the transmitters ground.
I am not getting any keying and don't see any change in voltage on pin 2. I
have tried a DOS program from Lyle (K0LR) and his program didn't switch any
of the lines either. Is there something I need to do in Windows to get the
port running??? I am ready to give up and go with a memory keyer real soon.
Thanks es 73's,
