Well, everything you know is wrong! NetMos used to be the PCI parport chip that was known to not work in EPP mode. (That really only applied to the NM9805 and maybe 9815 chips. But, it was a bad reputation.)
Now, we see that the Oxford OXPCIe952 chip doesn't work, or is at least different enough that the code we've been using for 15 years doesn't work with it. And, the NetMos 9900 chip works like a champ! So, the Syba PCIe parallel port uses the NetMos 9900 chip, and is quite affordable from such outfits as NewEgg and Amazon. The Oxford chip is used in such boards as Startech PEX1P, SIIG DP 1-Port ECP/EPP Parallel PCIe and the Rosewill RC-302E (I didn't even test this one, it uses the same chip.) I'm not sure what they've done to break it, but I put 0x04 in the DCR to write and 0x24 in the DCR to read, and have used this code since 2001. When the DCR has 0x24 in it, it will not produce the DATASTB/ pulse when there is an INB instruction executed to the EPP data port register. I will have to update my documentation on what parport cards work.
