hobbit: How to change the default client port number?

I can't find the information which I need in the list archive. Please
help me!!!  thanks!
 
 
Hobbit version:  4.2.0
 
I change port 1984 to 1937 on hobbit server for Big Brother was running
on port 1984.
change file hobbitserver.cfg:
BBPORT="1937"   
change file hobbitclient.cfg:
BBPORT="1937" 
It is work on hobbit server. But other server I have changed BBPORT in
hobbitclient.cfg on client, but it arrived nothing on the server, only
conn is well.
