Hello!

So i have this:

Code:
04:02.0 Serial controller: Timedia Technology Co Ltd PCI2S550 (Dual 16550 UART) (rev 01) (prog-if 02 [16550])
        Subsystem: Timedia Technology Co Ltd PCI2S550 (Dual 16550 UART)
        Flags: stepping, medium devsel, IRQ 3
        I/O ports at ec00 [size=32]
        I/O ports at e880 [size=8]
        I/O ports at e800 [size=8]


And the only relevant info i seem to find is to enable CONFIG_PARPORT_SERIAL, but that option is not available in my kernel version of 5.7.8-gentoo

Any ideas? I do have 16550 and 8250 alternatives enabled, but it does not work.

Thanks

ALF__,

Please post the output of
Code:
lspci -nnk
The k bit won't be very useful but the PCI vendor and Device IDs fed into google will identify the driver.

Kernel options are usually hidden until the things they depend on are selected. That works if you know how to get what you want.
To see and search hidden options, press the 'z' key in menuconfig. Thats a toggle.
You still can't select the hidden options but now you can navigate to them and read the Depends on: in the help to see why not.

-- edit --

PARPORT_SERIAL is still there. Its just hidden for both of us.
It looks like what you want too.

I've passed you the fishing line. Post back if the string is too short. :)

NeddySeagoon,

As always, thank you.

However, the first google results points to the now hidden PARPORT_SERIAL. But further down, on a Debian-site i found that it was the PARPORT_PC i needed.

So the card seems to be up and running now.

I did have ttyS0 to 3 before, but was unable to echo to it. Now S0 and S1 works. So it some how automatically "mapped" the ports to those.

Thanks! And, the fishing line was about long enough! :)
