I have written my own software in VB6 which successfully opens the ADC11 unit on LPT1 (port 1) on a Windows 98 system, but on a Windows 2000 machine, it reports and error - "Port not opened". PicoScope still works fine on the Windows 2000 machine, so why is my own software unable to open the ADC11 unit?
The ADC11 is a V3 and all the latest drivers have been downloaded and the correct OS selected during installation. In the BIOS, the port is set to SPP, 0378, IRQ 7.
Thanks for any help,
