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.
73's,

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.

73, Rik  ON7YD
