  Rev 1.5    2004.02.03 5:44:26 PM  czhower
  Name changes

  Rev 1.4    1/21/2004 4:03:54 PM  JPMugaas
  InitComponent

  Rev 1.3    15.9.2003 12:36:44  TPrami
  - Process information will be written in SendLogMessages if AUsePID
  is false

  Rev 1.2    15.9.2003 12:22:10  TPrami
  - AUsePID was not honored is SendLogMessage

  Rev 1.1    15.9.2003 11:05:26  TPrami
  - SendLogMessage was not sending Pid and name correctly. Now
  AText goes to the Content, not to the Text property

  Release history:

    divided SysLogMessage into this unit

}

{ ToDo:  Somehow figure out how to make a bound port and bound IP property
  in UDP Client.  This will probably require some changes to the Indy core
  units though. }
