[rtl] Using RTL on particle accelerator data aquisition. How to rewrite device drivers?

[Torge Szczepanek <cygnus@uni-bonn.de>]

Hi everybody!

I am newbie to RTL and to this mailling list.

I have to build a Linux system which is able to receive data from a
particle accelerator detector through FDDI. The incoming data should
then be stored (without any modifications) to a DLT tape drive. I found
that RTL would be the right choice to do that.
But the problem is, that I don't know how I can get data from the FDDI
or even write it to the tape. I know that it is not possible to simply
use open("/dev/dlt"... to do the job. I read the documentation about
devices and rewriting device drivers, but I didn't understand what to
do.

Can somebody explain how to rewrite a device driver?
Perhaps somebody has already a modified version of a FDDI device driver
or a dlt tape driver (i think not, but perhaps there is someone out
there)?
