I think we're at a disadvantage for not quoting the whole message
here... But you have two hex patterns in an LSAP list. The first
0x#### represents SSAP and DSAP patters. So if the 0D is in this part,
it's explicit. The second 0x#### represents a mask on the first two
numbers. So if the 0D is in here, then it may very well represent 00,
01, 04, 05, 08, 09, 0C, 0D inclusive.
In the ethernet-only world, that's really overkill. Most of those are
IBM-specific TR stuff. 00 is null SAP used for things like explorers.
In ethernet, you'll find 04 and 05 for SNA, F0 and F1 for Netbios.

But the 0x0D is the summary of 0x05,0x09,0x0D, Isn't it ?
