-- =========== ======== =================================================
-- 14-AUG-2003 Tim Hall Initial Creation
-- 10-MAR-2004 Tim Hall Add convert_crlf procedure.
-- Incorporate CRLF conversion functionality into
-- put_local_ascii_data and put_remote_ascii_data
-- functions.
-- Make get_passive function visible.
-- Added get_direct and put_direct procedures.
-- 23-DEC-2004 Tim Hall The get_reply procedure was altered to deal with
-- banners starting with 4 white spaces. This fix is
-- a small variation on the resolution provided by
-- Gary Mason who spotted the bug.
-- 10-NOV-2005 Tim Hall Addition of get_reply after doing a transfer to
-- pickup the 226 Transfer complete message. This
-- allows gets and puts with a single connection.
-- Issue spotted by Trevor Woolnough.
-- 03-OCT-2006 Tim Hall Add list, rename, delete, mkdir, rmdir procedures.
-- 12-JAN-2007 Tim Hall A call to get_reply was added to the get_remote%
-- procedures to allow multiple transfers per connection.
