Pico Universal Stepper Voltage questions

This is the onliy entry that relates at all to a parallel port.

01:00.0 Communication controller: MosChip Semiconductor Technology Ltd. PCI 9835 Multi-I/O Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic PCI 9835 Multi-I/O Controller
Flags: medium devsel, IRQ 21
I/O ports at d050
I/O ports at d040
I/O ports at d030
I/O ports at d020
I/O ports at d010
I/O ports at d000
Kernel modules: parport_serial

Yes. I think you are correct. Below is the dmesg output showing 2 parallel ports.

I will check for the pin headers and look for an adapter. I assume it will be more straight forward going forward to use the built in port than the pci one.
Thanks for your help. Dan

OK, so ONE of those addresses is the EPP parallel port, but I can't tell you which one it is.
You will have to try all of them.

Yes, if it exists (seems so from the lspci and /proc/ioports output) that could be easier.

Yes, the above output is still showing no communication. You SHOULD get a list of ONW board only at address 0, and then 15 "No Board". The above list shows a bunch of "Unknown" and other boards which are not present. That is wrong.
