From the man page:

 -M NetBIOS name
This options allows you to send messages, using the "WinPopup" protocol, to another computer.
Once a connection is established you then type your message, pressing ^D (control-D) to  end.
If  the receiving computer is running WinPopup the user will receive the message and probably
a beep. If they are not running WinPopup the message will be lost, and no error message  will

The message is also automatically truncated if the message is over 1600 bytes, as this is the
limit of the protocol.
                                                                                                              One useful trick is to cat the message through smbclient. For example:
    cat mymessage.txt | smbclient -M FRED
will send the message in the file mymessage.txt to the machine FRED.

You may also find the -U and-I options useful, as they allow you to control the FROM  and  TO
parts of the message.

See  the  message command parameter in the smb.conf(5) for a description of how to handle in‐
coming WinPopup messages in Samba.

Note: Copy WinPopup into the startup group on your WfWg PCs if you want  them  to  always  be
able to receive messages.
