The short answer is no, there's no CR/LF. However, the packets do come with a frame, and the frame has an escape rule that can result in escape characters being inserted. That's probably why you unexpectedly get changing packet lengths. The "right" way to pick packets out of the stream is to look for the framing bytes, 0x7E, which come at the beginning and the end of the packet.

The reason I ask is because I'm writing a program to listen to the SF port to save Mote data packets. Every now and again the data on the port comes out a different size and throws my program. If there is a termination character at the end of each packet I could resolve this problem. Also, I don't know Java so looking through the tools source code doesn't really help.
