I'm affraid the COTP reassembly code does not work correctly this way.
Please,have a look to attached trace file.
First, I don't think it is correct to assemble frame 4 and 8. Both frames 
are completed(not segmented) but reassembly code has decided to glue 
frames.Probably, reason is that frame 4 has TPDU number 0 and frame 8 has 
TPDU number 1.
Second, frame 6(TPDU number 0 and not segmented) has been inserted in 
segment list along with segmented frames 10,12,14,16(TPDU numbers are 
1,2,3,4)
