I'm using KISS (TM-D700) and Xastir is from CVS (compiled March 3rd). I 
ran into this when writing a small igate application. I noticed that 
some packets that looked identical to the eye weren't flagged as 
duplicates. I looked more closely and noticed there was extra whitespace 
at the end of those packets. Now I just ignore all trailing whitespace 
in duplicate detection.

I haven't really looked at the KISS packets coming in from the TM-D700, 
but rather looked at the packets as they come back via APRS-IS (I have 
Xastir set up to be an igate) via another TCP connection. Those packets 
arriving via APRS-IS that have my Xastir's callsign in the digipath 
often contain an extra whitespace character at the end of the packet. 
Often I also see the same packet gated to APRS-IS via some other igate 
and that packet doesn't have the extra space at the end. I guess it is 
also possible that the packets contain whitespace in the RF form as well 
and it is the other igate that is stripping away extra trailing 
whitespace in a packet before passing the packet onto APRS-IS.
