My experience has been that the above is showing that the PCI card parallel port base address is at 0xC030 and the extended register address is at 0xC020. If you put these addresses into showport: "sudo ./showport C030 C020 n" The output should show an ECR value less than 128 if the port is in SPP or greater if in EPP. Changing the "n" to "e" should set EPP if it isn't already. Once you get an ECR value greater that 127, you can test it with Jon's diagnostic program or run LinuxCNC. The 0x0378 address you may see is most often the address for the motherboard parallel port, with an extended register address of 778 (but the extended register could have a different address). -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
