              This  options  allows  you  to  send messages, using the
              "WinPopup" protocol, to another computer. Once a connec-
              tion 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 occur.

              The  message is also automatically truncated if the mes-
              sage is over 1600 bytes, as this is  the  limit  of  the
              protocol.

              One useful trick is to cat the message throughsmbclient.
              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 mes-
              sage.

              See the message command parameter in the smb.conf(5) for
              a  description  of  how to handle incoming WinPopup mes-
              sages in Samba.

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