Command Usage:
send &ltmsg_type> &ltdest> &ltfield1> ...

To send a control message halting RTgateway (as an example):
    MON> send CONTROL /control_channel_unique_subject "GW_STOP gwyA"

The send command constructs a message and sends it to RTserver for distribution to all RTclient processes subscribing to the destination subject. The message is specified in SmartSockets message file format. The outgoing message is not buffered, but is instead flushed immediately to RTserver for distribution.
