interface parallel port and serial port in WindowsXP on C

[yogi]

here is the way to interface in C language

http://www.embeddedtronics.com:80/public/Electronics/minidaq/userport/UserPort.zip

download this file and unzip it

then copy Userport.sys to WINDOWS\SYSTEM32\DRIVERS

then run USERPORT.EXE

u will get a message driver started

Now u do programming in C/C++/JAVA and interface in XP or other version of Windows.

this one worked with me,for parallel port tutorials see
