# I don't know whether CIMD is ever found by itself in a TCP connection. 
# I have only seen it myself as part of the Chikka login process, in 
# which the second and third packets (at least) are CIMD.  So I am not 
# using a '^' at the beginning.
#
# This pretty well explains the pattern:

# However, Chikka does NOT terminate the last field with a tab.
