# FOR UPDATING GLOBAL DEFAULTS:
Agent/TCP set windowInit_ 1
# The default is being changed to 2.
Agent/TCP set singledup_ 0
# The default is being changed to 1
Agent/TCP set minrto_ 0
# The default is being changed to minrto_ 1
Agent/TCP set syn_ false
Agent/TCP set delay_growth_ false
# In preparation for changing the default values for syn_ and delay_growth_.
