Hello everybody!
Please help me with my lpt0
When I try to put something to lpt0 I see the next:
```````````````````````````````````````````````````````````````
~# cat > /dev/lpt0

`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
