 * miniftp.cmd :
 *------------------------------------------------------------------
 * 03-16-93 originally by Patrick J. Mueller & Cliff Nadler
 *------------------------------------------------------------------
 * maxiftp.cmd:
 *------------------------------------------------------------------
 * 10-27-93  modified by Albert Crosby <[e-mail]>
 * v2 11-5-93
 *
 * Some changes and suggestions were added from Al Dhir's sFTP
 *
 *  Second release:
 *     Fixed a bug in handling filenames on FAT partitions
 *     Added some additional extensions to the BINARIES list
 *     Removed some debugging code
 *     Changed "colon mode" to MGET instead of GET
 *     Changed the prompt to display directory
 *     Added highlighting
 *     Added a new help screen for MAXIFTP ?
 *     Added the status command
 *     Changed default to NODISPLAY
 *     Added TOGGLE command and some settings
 *     Added command line options
 *     Added the nifty new TOUCH command!
 *     Get now accepts wildcards! (psuedo fn completion...)
 *     Added quoted strings
 *     Added a CREATE command
 *     Now uses the NETRC file
 *     Added a LCD command to change local directory.
 * Version 3
 *     Fixed TOUCH for VM and Windows_NT
 *     Added a SET command to change string variables
 *     Display pager in the SHOW command
 *     Allow user defined prompt
 *     Added more binary types
 *     Fixed getpasswd to allow spaces
 *     Now prompts before exiting if Ctrl-C is pressed
 *     Added MORE as an alias for the PAGE command
 *     Shell now uses COMSPEC rather than always CMD
 *     Initial comments in NETRC are treated as commands to MaxiFTP
 *     Comments after a machine command in NETRC are queued as commands
 *     Uses EA's to store history and longname
 *     Redial mode added
 *     BELL added to ring a bell at connect and after a file transfer completes
 *     VISUAL mode began.  Very primitive.
