Hm.

These are going to be determined by linux when it loads parport_pc.  If
you load parport_pc before running any of your manipulation programs and
it shows PCSPP,TRISTATE that implies to me that the linux kernel parport
driver (which embodies a lot more wisdom than the drivers in emc2)
thinks the port is not EPP capable.

Re: [Emc-users] PCI parallel port EPP problem with SUN1888 chipset

2010-01-20 Thread Jeff Epler 
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:
 *  Bit 0 of STR is the EPP timeout bit, this bit is 0
 *  when EPP is possible and is set high when an EPP timeout
 *  occurs (EPP uses the HALT line to stop the CPU while it does
 *  the byte transfer, an EPP timeout occurs if the attached
 *  device fails to respond after 10 micro seconds).
 *
 *  This bit is cleared by either reading it (National Semi)
 *  or writing a 1 to the bit (SMC, UMC, WinBond), others ???
 *  This bit is always high in non EPP modes.
 */

/* If EPP timeout bit clear then EPP available */
if (!clear_epp_timeout(pb))
return 0;  /* No way to clear timeout */
...
}

It detects ECPEPP (that is, EPP mode where you must manipulate ECR to enter and
leave it) by doing the ECR write and then the EPP test above:
static int parport_ECPEPP_supported(struct parport *pb)
{
struct parport_pc_private *priv = pb-private_data;
int result;
unsigned char oecr;

if (!priv-ecr)
return 0;

oecr = inb(ECONTROL(pb));
/* Search for SMC style EPP+ECP mode */
ECR_WRITE(pb, 0x80);
outb(0x04, CONTROL(pb));
result = parport_EPP_supported(pb);

}

Of course, all this code is dependant on CONFIG_PARPORT_1284, and I don't know
whether your kernel has that enabled.

I'm using this card for the soft stepping. It works at 50 KHz without
any problem (base_period=2 and double stepping). Does this means
that there is no need to force it to EPP mode? Will it cause problem

EPP mode is not required or used by hal_parport.  Is there documentation
that led you to think the opposite?

EPP is suggested in some wiki pages and in some e-mails from the EMC
list. But after I read the docs and the e-mails again, I saw that I
misunderstood these. These are for the PICO and Mesa cards.

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.

 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 and look at /proc/ioports for changes to 
 the former state (risk a few sheets of paper ro print the file contents). 
 Test the port if you suspect an address to work. Then put in the other 
 cards one after the other, rebooting and trying each time. Weary job.
 By the way: my addresses changed from a400 and b000 to b400 and d000 when I 
 moved the PC from one room to another...;-)
 
 Best regards
 Peter Blodow
 
 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: You will find addresses like a400, b000 up to d000.
 My card supplies 6 such possibilities to chose. Behind the valid address
 EMC had put in a line stating hal parport as a comment. That's the one.
 If you are not sure, try them all with stepconf: insert the address to be
 tested, doubleclick on Continue to get to the X-Axis page and test axis.
 If the re is no motion, return with doubleclick and try the next address.
 Within a minute I had tested all 6 addresses given.
 Don't save the stepconf five when leaving in case you have made unintended
 changes.
 
 Note that this address you found can change in case you play with BIOS or
 Cmos-Setup or install some other devices.
 
 I made myself a printer port test plug with LED's (from a serial null
 modem) so I can see what's happening on the lines without the whole machine
 setup.
 
 Best regards
 Peter Blodow

Will - Where about are you located at?  With Chris' comment in mind - I've
got a single port Netmos based PCI LPT that is going to be swapped shortly
for a dual port Netmos (once I get over to my local shop _ I give them
occasional business over Newegg since I don't want them to go under).  I'd
be willing to part with the single unit for a steal (depending on your
location that is - if shipping is more than the board's cost...)  Feel free

 I don't think it's anything you're doing -- I don't like this
 Serial controller identification.  Something is goofy.  Maybe try
 another type of card?

Re: [Emc-users] PCI Parallel port

2009-04-07 Thread Peter blodow 
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 and look at /proc/ioports for changes to 
the former state (risk a few sheets of paper ro print the file contents). 
Test the port if you suspect an address to work. Then put in the other 
cards one after the other, rebooting and trying each time. Weary job.
By the way: my addresses changed from a400 and b000 to b400 and d000 when I 
moved the PC from one room to another...;-)

Best regards
Peter Blodow

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: You will find addresses like a400, b000 up to d000.
My card supplies 6 such possibilities to chose. Behind the valid address
EMC had put in a line stating hal parport as a comment. That's the one.
If you are not sure, try them all with stepconf: insert the address to be
tested, doubleclick on Continue to get to the X-Axis page and test axis.
If the re is no motion, return with doubleclick and try the next address.
Within a minute I had tested all 6 addresses given.
Don't save the stepconf five when leaving in case you have made unintended
changes.

Note that this address you found can change in case you play with BIOS or
Cmos-Setup or install some other devices.

I made myself a printer port test plug with LED's (from a serial null
modem) so I can see what's happening on the lines without the whole machine
setup.

Best regards
Peter Blodow

I think I have done something similar to this by changing the .hal file to the 
four different addresses that were shown via lspci -v.  0xc400 caused errors 
and the other three would allow axis to start up but there would be no output.

So with the above data shown from lspci, is there anything in there besides the 
addresses that could be used to figure out what is happening?

Thanks for the help so far!

Just checked, there is a file /etc/modprobe.d/emc2 that does have the line

Re: [Emc-users] PCI Parallel port

2009-04-05 Thread Greg Michalski 
Hi Will - 

I'm a bit tired but I recall having to try all the addresses to get my
Netmos card to work - which you've already done.  Looking at my config file
I have quotes around my addresses (I have 2 ports, one an input only so that
might be why - I'd have to go back and read docs).  Also the dmesg file says
something about the module parport - did you try commenting out the loadrt
prob_parport?  Not sure if this is what it refers to.  Sorry I can't be of
more assistance at the moment.

learn
 more about it, using a small table top mill that I built using various
parts.  Wanting
 to branch out into a cheap I/O upgrade I decided to purchase a PCI

 card.  But I have run into a problem getting this going.
 
 After installing the card, I used sudo lspci -v to find out the address,

 I have tried the other three address's listed.  They allow Axis to start
but cause no
 outputs on the parallel port card.
 
 Also, after searching the Gmane archives, I found info about Netmos cards
but nno
 luck on VSCom.
 
 I am sure that I missed some steps in the setup fo this card but am unsure
as to
 what they are.
 What are the steps that I missed to do and what can I do to track them
down?
 
 Thanks,
