I get the impression you will be driving steppers direct. EPP isn't needed 
for that as the input and output pins are in separate groups in the other 
modes.

I am using, or was till just recently, a startech board, worked as 
expected.  I put a D525MW based machine on the mill recently.  You will 
need to change the ports address from the default of 0x0378 though, I think 
in my case to 0xD000, but check your dmesg for the correct discovery 
address after putting it in and booting up.

Jeshua;

It's in hexadecimal, so 0xc090 would be fine.

(I'm no expert, but…) I just added another card to my system, and this card has 
2 parallel ports on it. Each connector goes to a port; the issue is getting the 
correct address with the correct port; either trial and error, or just read the 
manual!

(my second port came in at some high number like the 0xc090 or something like 
that; away far away from the 0x378 or 0x278 or whatever the "usual" is. I 
connected it to a cnc4pc MPG controller, and it worked first time)

Thanks! I just wasn't sure to put a 0x in front or what.

I just put in 0xc050 and it works!

Honestly I do not know. I guess it could be 0xc090, but I would
encourage You to try those remaining too, if this does not work. If
none of them work with 0x in front, then I am wrong. As simple as that

Well according to this datasheet:
http://snebulos.mit.edu/projects/voila/docs/datasheets/Oxford_QuadUART.pdf 

there is an EPP port in there somewhere. That is if the report above is
correct about the ...

Geeze guys, you beat me to everything I had.

The only thing else that comes to mind is I believe parport_pc assigns
the port by number so if it doesn't show up in lspci the port by number

Or not.

The info from that link is the same as the box I have.

But 'lspci' shows more than one entry for that card which I omitted to include:

08:00.1 Non-VGA unclassified device: Oxford Semiconductor Ltd OX16PCI954 (Quad 
16950 UART) function 1 (parallel port) (rev 01)

Capabilities:

Sorry for being dense, but based on that, what address would I use for the base 
address in the stepper configuration? 

0c050?

Whatever you have, it doesn't match the description in the Amazon link 
you sent (a single parallel port incorporating an OX16PI952 chip).

The OX16PI954 chip reported by lspci supports 4 uarts and a parallel 
port. see 
http://snebulos.mit.edu/projects/voila/docs/datasheets/Oxford_QuadUART.pdf 
, which says

"The OX16PCI954 is a single chip solution for PCI-based
serial and parallel expansion add-in cards. It is a dual
function PCI device, where function 0 offers four ultra-high
performance OX16C950 UARTs, and function 1 is
configurable to offer either an 8 bit Local Bus or a bidirectional 
parallel port"

I don't have a clue why the parallel port doesn't show up 
automagically.  Perhaps it's that last bit about configuring function 1 
that's at issue, but that's pure speculation on my part.

Kent

EPP should only be needed if you have an add on FPGA card thatq communicates 
via EPP


can you just select the first LPT port via stepconf? I'd try that first

EPP mode is needed only and exclusively for external fpga boards.
If Your goal is software step generation, then You do not need the EPP mode.

> So can anyone suggest what I might have to do to use the card with EMC2?

I guess that one of these c090, c080, c070, c060 or c020 is the port
address, which should be specified in the HAL file (sorry, I am not
that smart to know, which one exactly; trial-and-error method is my
best friend in such cases).
Other than that - treat it as usual parallel port.

Thanks Peter.

So, how did you determine that address to use for the stepper config?

> Why do you need EPP?

Perhaps I am wrong, but I interpreted that the wiki was stating that EPP is 
required:

"Parallel port cards allow the addition of parallel ports beyond the built-in 
port on PC motherboards. These may be used for realtime functions such as 
software PWM and step/dir, or for user functions such as controlling coolant, 
tool changers, relays, etcetera. Nearly any card will work with pin changing

The Oxsemi (well PLXTech now) OX16PCI954 does support EPP (I have one and it

Why do you need EPP?
