I did some tests already a long time ago and sent the results to somebody 
of the community. I repeat it here to let you know how difficult the 
problem may be to solve:

I have an external IrDA adapter connected to the serial port and I spy via 
"hardware". That means I connect the RX and the TX pin to the RX pin of two 
additional COM ports and trace the serial communcation with a commercial 
application under Windows, write the data stream to a file and then analyze 
the FBUS (not in this case :-() data stream with a special program written 
by myself. As I could not find any valid FBUS frames in the data stream I 
had a look to the hex data and found "OBEX:IrXfer" there, which seems to be 
the way the PC-Suite communcates with this handset. After digging into the 
Symbios documentation I found out, that they *do* support Obex (but they 
also support mRouter among others).

My aproach would be to write a Obex spy (as the Obex frames are well 
documented) analysing the raw data captured from the IrDA device on the one 
side and - on the other side - have a nearer look for the documentations 
which may be available from Symbios (as Nokia did not add that much to the 
Symbios kernel for the 7650 - they even support GSM, SMS and other things 
directly via the kernel and even bluetooth, but without the audio profile - 
this is the reason why you can not connect with a bluetooth headset with 
the 7650 (Symbios does not support this profile and Nokia did not add 
something to the kernel as far as I can see that).

But having all the data stream analyzed and implemented which is running on 
the PC-Suite does not help that much: The PC-Suite does *nothing* with real 
time events - so you can not send a SMS via the software, you do not have 
information about the status of the phone ....

Symbios seems to support file i/o related things in their kernel only, this 
might be the reason why there is nothing beyond that in the PC-Suite.
