Status update:
- The error is still reproducible on Polar ProTrainer V5.40.171
- The data transmition in Polar Pro Trainer has type=SOCK_STREAM. It works like
this:
   - WS2_sendto some bytes
   - WS2_recvfrom some bytes
   - 5-7 times: WS2_sendto zero bytes
   ...
   - WS2_sendto some bytes
   - WS2_recvfrom some bytes
   - 5-7 times: WS2_sendto zero bytes

- The errno ENOTCONN (107) is created in the Linux IrDA stack in
net/irda/irttp.c, function irttp_data_request:
http://lxr.linux.no/linux+v2.6.35/net/irda/irttp.c#L590
- As already mentioned above (See comment #79) a kernel log entry is written
when buffer size is zero: 
....irttp_data_request: No data, or not connected
- The check for skb->len == 0 is already part of the Linux kernel since IrDA
stack has been included in linux-2.2.0 (26-Jan-1999).
- The Windows/Linux AF_INET stack returns 0 when sending a buffer with size 0
(Tested on all 32/64bit Windows Versions, Linux 2.6.32)
- The Windows AF_IRDA stack returns 0 when sending a buffer with size 0 (Tested
on Windows XP)

Next steps:
- I've posted a message to the Linux IrDA newsgroup to evtl. get more
information about the Linux IrDA stack, waiting for feedback:
http://thread.gmane.org/gmane.linux.irda.general/1643
- I will write a wine test for AF_IRDA to get the current behavior on all
Windows versions
