Hi all,
I am resending this with [PATCH] in the subject.
This is specifically for the 2-port db9 (no parallel port) version of
the card.
I purchased a two port PCIe serial board. Linux didn't seem to notice
it. I dug into the parport and tty/serial/8250 and added the PCI ID's.
Now the ports are working just fine.
I am also sending this patch to the linux-parport list since it touches
files in both locations.
...Jeff
