Looking at the log, it is the Linux side that doesn't answer
the TTP request. As far as I can see, the request is proper. It look
like a genuine bug in the stack (surprise, surprise).
Now, we need to know if the bug is in IrTTP or IrComm. Could
you try to do some obex put from Palm -> Linux instead of the IrComm
connection and see if there is problem or not ?
Another thing : you need to tell us what is the kernel version
you are using and what messages you see in the log. Also, ppp has a
debug flag that can help.
Overall, Dag is much more knowledgeable about IrComm, so I
guess I'm waiting to see what he has to say...

Jean
