Hello everybody!

Please help me with my lpt0

When I try to put something to lpt0 I see the next:

```````````````````````````````````````````````````````````````
~# cat > /dev/lpt0
Oct 30 01:41:58 lizard /kernel: lpt flags 0x0
Oct 30 01:41:58 lizard /kernel: lpt flags 0x0
/dev/lpt0: Device busy.
Oct 30 01:42:02 lizard /kernel: status 4e
Oct 30 01:42:02 lizard /kernel: status 4e
~#
```````````````````````````````````````````````````````````````

`fstat /dev/lpt0` shows empty table.

Here it is part of dmesg's output:

```````````````````````````````````````````````````````````````

Here it is part of my kernel config:

```````````````````````````````````````````````````````````````
device          ppc0    at isa? irq 7
device          ppbus
device          lpt
options         PPC_PROBE_CHIPSET # Enable chipset specific detection
options         LPT_DEBUG       # Printer driver debug
options         PPC_DEBUG       # Parallel chipset level debug
```````````````````````````````````````````````````````````````

I tried w/o PPC_PROBE_CHIPSET result was the same.

What can you advice?

May be I should set my chipset to NIBBLE mode?
But I don't know how.

I'm waiting for any propositions
Anton
