| From: Darius Moos <moos@degnet.baynet.de> | Hi, | | have you tried to assign every printerport its own IRQ in the | kernel-configfile ? | Actually, no. When originally configured, lpt0 was irq 7, lpt1 was polled (as was lpt2 when it was alive). Under these conditions, lpt0 was extremely sluggish. The traditional advice for that situation was to switch the interrupt-driven port to polled with lptcontrol (has this changed?). And in fact printing worked equally well on each port. My experience in the past is that interrupt problems show themselves fairly early (as in minutes) rather than late. Perhaps I need to reconsider... Some advice was issued previously about hacking the interrupt lines directly on the board(s) based on ISA bus layout. Though an EE by degree, I use it little in the past few years, and I'm loathe to chop on company property as an experiment, especially if it fails, so that approach is so far postponed. Nonetheless I can boot -c this weekend and reconfig the running kernel to use irq7 for lpt0 and irq5 for lpt1, and see how it flies. thanks for the advice, larry
