Information on DLPORTIO.DLL --------------------------- If you want to use the PARALLEL port interface, you need an additional DLL called dlportio.dll. If you're not planning to use the PARALLEL interface, you don't need this DLL. Due to licensing issues we are not allowed to provide the required DLPORTIO.DLL with CRRCSim. This means that you have to install it from a separate package. Download it from http://www.driverlinx.com/DownLoad/DlPortIO.htm and install it as described on this page.
