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
