I tried to write 0x80 to 0x1002 and 0x101A today. The results are as
the followings:
# ./epp 0x101a
ECR address: 0x101a
initial read: 0x00
write: 0x80
final read: 0x00
# ./epp 0x1002
ECR address: 0x1002
initial read: 0x15
write: 0x95
final read: 0x95
There are no change for the parport modes:

Hm.
These are going to be determined by linux when it loads parport_pc. If
you load parport_pc before running any
The Linux parport_pc driver seems to detect epp mode based on whether it
is possible to clear the EPP timeout bit:
static int parport_EPP_supported(struct parport *pb)
{
const struct parport_pc_private *priv = pb-private_data;

* Theory:
Of course, all this code is dependant on CONFIG_PARPORT_1284, and I don't
know
whether your kernel has that enabled.
CONFIG_PARPORT_1284 is enabled
$ grep CONFIG_PARPORT_1284 /boot/config-2.6.30.5-rtai
CONFIG_PARPORT_1284=y
I'm using this card for the soft stepping. It works at 50 KHz

Hi all,
I have a PCI parallel port card with SUN1888 chipset (Digitus). There
are two ports on it. I can't switch it to EPP mode.
Port1 is at 0x1018 and Port2 is at 0x1008
I tried to write 0x80 to base_address + 0x402 using the base address
0x1018 and 0x1008 but it doesn't work. I always read
What does linux parport_pc say about ports?
Presumably the base and base_hi ports all have to be from the set of
I/O ports named in lspci, so the base_hi ports must be the 1000 and
1010 addresses if the xxx8 addresses are the bases.

Shouldn't you be writing at base_hi + 2, not at base_hi?

William,
if you can't find the correct memory addresses of your card then try the
hard way: remove all PCI or ISA cards and everything else that's not
necessary to run the bare PC. Boot

Hello William,
last week I had just the same problem. It turned out that some other device
claimed the same addresses as my Netmos 2 port card. This particular one
may be hard to find. First, use lspic -vv or even lspci -vvv to get more
information than with lspci -v.
Look at /proc/ioports:

I just tried starting up this config with loadrt prob_parport commented out but
it still errors out.

Lars,
I have gone through that page but have not found anything that would show the
problem, maybe a second look is what needs to be done.
