Actually, you want an interrupt-driven port in any case, but there are different ways of handling the interrupts for network versus printing use, and the default kernel is set up for networking (for the reasons described above). What you really want to do (the advice is somewhat version-dependent, but definitely applies to 3.x, and I *think* to 4.0 as well, although I can only check the former) is recompile the kernel to use "tty" instead of "net" in the ppc device description. Then you run your printer in interrupt mode, which should be a lot more efficient than polled mode. Some hardware won't support interrupt mode anyway, but you want to use it if you can. > BTW: It would be nice if the port would switch automaticaly when you open > the lpt device or the plip device. Yes, that would be nice. Got diffs? Be well. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
