Hello,

could somebody include lines of C++ code where I can send data to the
parallel port ? I am using windows vista 64 bits and Visual C++ 2005.

I have already tried _out, outportb and assembler but I could not make any
code work .... I had the same code running on a XP computer but Vista is
killing me.

Thanks a lot in advance,

Mariano

Use WDK to write drivers, not Visual Studio.
See "Getting started with Windows drivers" in the WDK documentation.
To write a byte to i/o port, use WRITE_REGISTER_UCHAR macro.

I don't believe you had your code running on XP (other than running 16-bit
in VDM).

Look for CreateFile function, device "PRN" or "LPT1", "LPT2", etc.
