patch for netmos based serial devices

Hi all,

I recently aquired a serial card based on the netmos 9845 chipset which boasted linux support. Sadly the chip is currently not supported in 2.4.20. I found the necessary patches on the internet and ported them to wolk 4.10-pre7.

The patch is based on work by RedHat and a mail found on LKML from Sept. 2003 sent by [email protected].

Mit freundlichen Gruessen / With kind regards,

Olaf Unterkofler
