It depends. If you want to use the parallel port pins for slower speed general purpose control, such as for turning a coolant pump On and Off, or sensing button or MPG input, then your card should be fine. If you want to communicate with a parallel port FPGA signal generator, it most likely will not work. > I would like to use it as a second port, but when I start the > Linuxcnc program, the program gives failure after giving of I/O setup > and portadress.

It should list your card and a range of addresses. The list shows the starting address for the control and extended register blocks for the parallel and serial ports. You can try each address with the the linuxcnc loadrt command until you find the one that works, but I usually also check the dmesg output: dmesg | grep parp dmesg lists messages as the operating system loads. Usually there is a driver program that looks for parallel ports and sets them. grep filters out the lines that don't have "parp" in them. (The | symbol is a pipe that runs dmesg output into grep's input.) My output on this computer looks like this: > kwallace@jupiter:~$ dmesg | grep parp > [ 13.695523] parport_pc 00:07: reported by Plug and Play ACPI > [ 13.695576] parport0: PC-style at 0x378 (0x778), irq 7, dma 3 > [PCSPP,TRISTATE,COMPAT,ECP,DMA] > [ 13.792725] lp0: using parport0 (interrupt-driven). > kwallace@jupiter:~$ which shows that parport_pc found a card with a control register at 0x378 (with and extended register at 0x778). For system use, the port was labeled lp0, which can optionally be used by linuxcnc's loadrt rather than the register address. In this case the motherboard's local port, 0x378, is listed. Recently, I installed a parallel port card which dmesg did not list. This was likely due to there not being a proper linux parallel port driver for this card. The card worked anyway by trying each address in the lspci output.

EPP may also be needed for use with a Gecko G540. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
