I stuck the drq 3 into the 'controller ppc0' line. BTW, since LINT was changed, there's now no indication as to where to stick the dma channel info, for users. Anyhow, now my config looks like: controller ppc0 at isa? port? tty irq 7 drq 3 controller ppbus0 device lpt0 at ppbus? device plip0 at ppbus? device ppi0 at ppbus? device pps0 at ppbus? There are a couple of things that have happened that strike me as worthy of comment. Here's my relevant dmesg part: ppc0 at 0x378 irq 7 drq 3 on isa ppc0: SMC FDC37C665GT chipset (ECP/PS2/NIBBLE) in COMPATIBLE mode ppc0: FIFO with 16/16/15 bytes threshold ppb0: IEEE1284 device found /NIBBLE/ECP Probing for PnP devices on ppbus0: ppbus0: <HEWLETT-PACKARD DESKJET 690C> MLC,PCL,PML plip0: <PLIP network interface> on ppbus 0 lpt0: <generic printer> on ppbus 0 lpt0: Interrupt-driven port ppi0: <generic parallel i/o> on ppbus 0 lppps0: <Pulse per second Timing Interface> on ppbus 0 Notice how the ppbus finds and correctly IDs my printer (yea!) but then the lpt0 and ppi0 lines find generic ... this is a little odd, isn't it? Even if the lpt0 and ppi0 parts are less intelligent, they should share info to at least some degree, shouldn't they? 2nd note ... you said I should use lptcontrol -e. I did that, exactly, and it came back to tell me that it had switched me to extended mode (which I expected) AND to polled mode (which I neither expected nor wanted). The man page says that only one action is taken at a time. I was able to switch on the interrupt mode again (which I did want) by using the -i switch (advertised correctly on the man page now) but isn't this wrong, switching to polled mode like that on entering the -e? Last thing ... I did the 'cat /dev/lpt0' like you asked. No response whatsoever, the prompt just came back. I did this both before and after all the changes done with lptcontrol, each and every time, but the exact same response, nothing. Like typing echo. No status. Something incomplete yet? This isn't criticism, this is the feeling of a child at Christmas opening new toys, but wondering if maybe there's more under the tree I haven't quite spotted yet. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run picnic (FreeBSD-current) (301) 220-2114 | and jaunt (Solaris7). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
