I don't know if it is the best way to see the source but, you might try here: http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/hal/drivers/parport_common.h;h=fc498dc973e2813508fe251555c55f3c7ef57e45;hb=e526d8d7369c7cf5f9b113b3080333a871e63108 (Short URL) http://alturl.com/dff6o Click "tree" on the top of this page to go up the tree. I know very little about the parport driver but I thought this might get you started. There are other parport FPGA drivers in the tree (Pluto and Mesa) using EPP (problems with PCI parports though).
