I am seeing a parallel port being detected in the boot logs: Nov 2 15:50:31 src@localhost kernel: : parport_pc 00:08: reported by Plug and Play ACPI Nov 2 15:50:31 src@localhost kernel: : parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA] But, I don't see any devices in /dev that are the parallel ports. Do you know what I need to do to be able to see parallel port devices? Or are they under a different name? I saw in udev configuration that it can be /dev/lp[0-9], parport[0-9], or irlpt[0-9]. -- Thanks, Brad Landis |

Hi. It's usually called /dev/lp0 but I've found that my server doesn't create it for some reason. That said, if you use mknod /dev/lpt0 c 6 0 that then allows you to use it. Hope that helps, Chris.

Well, that creates a device, but when I try to write to it, it just hangs. I think /dev/lp* requires /dev/parport*. I tried creating it using `mknod /dev/parport0 c 99 0 -m 660`, but it says "No such address or device" when I write to it. Users who have had this problem are finding that the ppdev module is required, but it's not installed on Devil Linux. On Wed, Nov 2, 2011 at 5:59 PM, Chris Grove <dl...@ki...> wrote: > Hi.

`modprobe lp` adds /dev/lp0, but /var/log/messages says "kernel: : lp0 off-line".

This was in dmesg: parport_pc 00:08: reported by Plug and Play ACPI parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA] Actually, I guess I can just use /dev/port, and create a program that uses 0x378 on /dev/port to get to the parallel port. I think that was working using lcdlinux in DL 1.2.15, so I can create my own program to access it myself. If this helps any, I noticed in Redhat that they have a file /etc/udev/makedev.d/50-udev.nodes that creates parport0-4. It would be nice to have working, but I guess not a lot of people need it.
