Correct me if I am wrong, but the only reason for putting a LPT port card into EPP mode is to make it compatible with a device like the Mesa 7i43.
If you are using the card for step and direction I don't believe you need to use EPP mode. I have found the Netmos chips to work fine for step and direction and I/O, but I understand they have major bugs when using EPP mode. I have not had any problems with Mach3 and the Netmos 9805 type chips. The last time I did the LPT card hunt I found the Rosewill card that worked well and I bought 4 of them.. http://www.newegg.com/Product/Product.aspx?Item=N82E16815166005&Tpk=rosewill%20rc-302 $10.99 at Newegg. Gotta love the price if nothing else. :-) Dave On 9/14/2011 4:21 AM, Schooner wrote: > Hi > > This was a vexed question for me after I made a pendant and need more IO > to work it. > > None of the Parport IO cards I tried would not work at all, the problem > was getting them to work in EPP with pins 2-9 as inputs. > > I found previous entries from Jon, Kirk and others on this subject. > By repeated experiment; setting bits for EPP mode, pre-loading parport > drivers and then unloading before EMC, even setting the write flag for > the device under /proc/bus/pci/???
