Yip, have done, but this and all the other documentation I can find out 
there is missing a few key parts.  I've been unable to find _any_ 
documentation on PADP or DLP on the Palm site.  They do describe SLP, but 
under a different name.

Both pilot-link and coldsync handle last fragment loss 
differently.  pilot-link will stop transmitting the current packet even if 
it is half way through if it gets a unexpected data packet.  coldsync will 
ack and drop the incoming data fragment, then begin retransmitting its 
packet from the start with a new XID.

Both use the same XID for all fragments in a packet.  Interestingly enough, 
a real Palm handles the XID changing for each fragment fine.

Well, this seems close enough for now.  Thanks.
