hi, i want to use paralel port to control some instrument device. i already read help tutorial for configure this port. but why error result always appear when use comand: daqhwinfo ? and why "winio"-drivers not appear when open device manager non plug and play device (i already use show hidden devices)? i use HP laptop with serial and parallel port installed, windows XP, matlab R2006a, and log in as a administrator.
many thanks agung

What error shows up when you use daqhwinfo ?
daqhwinfo is part of the Data Acquisition Toolkit. Do you have that toolkit installed and licensed?
