This is what I expected :-(((

Hmmm, my test gave different results: 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.

Yes, I know, I *only* work under Windows (because of my commercial 
application Cellular Essentials - see at www.demmel.com )

What next?
