[ag-automation] OSADL FDDI remarks

[Peter Soetens]

Dear list,

We're looking for a small C library which allows to communicate different 
kinds of 'data' over any kind of bus (CAN, Ethernet,...) from device A to 
device B and the other way round. We're happy with 'hardcoding' the link from 
A to B in the lowest layers, so no XML-configuration required yet. Instead of 
reinventing the wheel, we're taking a look at the FDDI library. 

It looks like FDDI development stopped at the point where it got 
interesting :-). It can 'discover' and 'command' devices, but not exchange 
data (process variables). There are two use cases in the tests directory 
which define the API for the to-be-written LDI. 

 * Is there any implementation/beta code of the LDI interface yet ? 
 * Could you comment on the 'readyness' of the LDI API in the use cases, 
meaning, is it ripe/complete/final ? 
 * Also, is there by any chance uncommited code/documentation/examples ? We're 
basically reverse engineering the code to understand what's happening (which 
is ok given the small amount, but still...)
 * What's the relation with FAPIA, which is written in C++ ?

I thank Robert in advance for his answers :-)
Peter
