Data traffic to the MobiLink server is routed through the M-Business server.
If "host" and "port" values are null, ULPod automatically sets it to the current M-Business Server host and port.
"url_suffix" is the same "url_suffix" set in the sync.conf file of M-Business Server.
"additional" is for additional stream parms. Since this call overides the previous stream parm setting by setStreamParms(),
this argument gives caller a chance to add whatever additional synch stream parms that is otherwise lost.
