Second parallel port communication was created by thatguy
I am looking at options for breakout boards and planning my computer setup. I want to use both a THC and an MPG. I can tell that I'm going to run out of I/O on many of the cost effective boards. I've noticed there are some MPG interface cards available that hook up to a second parallel port.
What I'm planning on right now is for motor signals, limits, and THC to be on one breakout board via a single parallel port and then to run an MPG to another parallel port. Is LinuxCNC configurable to that or do I need to formulate a different plan.

Yes, linuxCNC can support up to 8 parallel ports

Hi Thatguy,
My advise is too use someting like this : www.allekabels.nl/pci-kaart/4974/1084957...art-2x-parallel.html
It works faster then using 2 separate pci ports.

For saving your time in hal section :
#find parport adres : halrun => lspci -vvv or type
#find parport adres : dmesg | grep par
#one parport
#loadrt hal_parport cfg="0x1110 out"
#dual parport
loadrt hal_parport cfg="0x1110 out 0x1120 out"
