1. What is INET?
----------------
INET consists of a DOS and a Windows implementation.
INET's main function is to be a terminal emulator, but
added to that you get three different print servers and 
print clients, FTP server and client, some test servers,
mail and many more.
INET implements a TCP/IP stack and supplies an API (DOS)
or WinSock (Windows) interface for third party applications.
INET supports multiple serial and LAN connections.
INET can be used as a very cost effective IP router or gateway.
INET can trace LAN traffic like a scope or sniffer for
problem solving.
Included are the following emulators: 327x, VTx00 (incl. ANSI),
D211, Wyse 50 and HP 700. Also available are ET 1100 and UTS60.

2. Enhancements since version 2.
--------------------------------
For users upgrading form an early version 2, we list
some of the major additions to INET for DOS.
(See the INET2.UPD file for a more complete list.)

A custom defined user menu with hot keys can be defined in 
the startup file, shielding users from the normal INET menus.

More shortcut key strokes have been implemented for the menu
selections in INET: Using Alt with the menu hot keys will jump
immediately to the menu item. 

A large memory model version of INET called INETL is included to
do better memory management for a PC used as a gateway with many
connections.

A minimum version of INET called INETM is included. INETM requires
less memory. INETM does not support serial lines and test servers.

The FTP client has been improved to handle batch processing.
The FTP client has been enhanced to allow multiple file
transfers to continue in the background when the session is not selected.
FTP server can do directory lists in UNIX format.
FTP server and client can use passive mode for fire walls.

SETHOST.EXE is a utility which simplifies network management by mapping 
host names or IP addresses to the hardware address of network interface
cards. 

TN3270E extended data stream is supported with printing.

A Domain Name Service (DNS) resolver has been implemented. 

SCO propriety ANSI sequences for line drawing and
VT Cursor Keys Mode (DECCKM) are supported.

SRPRINT.EXE is a TSR to access a serial printers via INT17.

An UNIX Line Printer Daemon server has been added to INET to
enable many LPR clients to print to Inet for DOS.

Two new interface types i.e. 'mdd' and 'aslink' have been
defined to enable dial-up operation to different networks
using SLIP.  The commands to be used in modem scripts
were expanded.

Keep-alive has been added to all TCP servers.

BOOTP has been implemented. 

The SEND-LOCATION Telnet option has been implemented. 

The ping command can take a /s=<bytes> option to enlarge the data 
added to the ping packet.

Multi-ring support for TokenRing was added.

Improved RIP supports many more scenarios where RIP is required.

RLOGIN has been implemented. 


3. INET specifications
----------------------
A full list of specifications is in the INETSPEC.RTF 
(in Rich Text Format) or INETSPEC.TXT file.
The Windows version has the information in INETINFO.WRI.

4. Updates, enhancements and documentation errata.
--------------------------------------------------
Corrections to the printed documentation are in the ERRATA.RTF 
(in Rich Text Format) or ERRATA.TXT file.
If you are updating from a version 2.xx, see section 2
in this file.
Documentation of new feature is given below.

v.3.01	96-10-02 Routing problems fixed.
v.3.02	96-10-03 Dial-up @a command added.
v.3.03	96-10-15 /x= in telnet command
v.3.04	NET_AS_ERROR reports kernel unloading in Rinet 
v.3.05	Sub-net broadcasts
v.3.10	Version numbers synchronized.
v.3.11	97-01-01 FTP server fix, implement CDUP command.
v.3.12  97-01-23 Fix handling of invalid LPD control files.
                Remove extra CR characters in log file.
v.3.13  97-01-30 Implement RIP version 2. 
	Change 'rip advertise' command:

         	rip advertise <time> [1|2] [self]

         '1' or '2' specifies the RIP version to use for advertising.
         On receive both RIP version 1 and 2 datagrams will be used. 
         Multi-cast is NOT implemented. Broadcast is used instead.

v.3.14  97-02-01 Implement RIP version 2 even better  :-) 

v.3.15  97-02-27 Add ability to trace loop back.

v.3.16  97-04-04 FTP server takes paths relative to login directory.
		"Too many users" message will not be given erroneously.
                Remove extra CR characters in log file.

v.3.17  97-05-15 Modified to generate ICMP error messages for third
		party trace route implementations written contrary 
		to the specification as in the ICMP RFC.
		Fix for TokenRing ARP.

v.3.18  97-05-19 Make the Enter-key re-definable as required for the
		Comrades Marathon registration hardware.

v.3.19  97-05-21 Enhanced security on remote console:
                It is possible to start the remote console server and 
                not allowing a remote person to get access to your
                screen without your active permission.  To activate it
                set your remcon password in INET.UPW to something
                starting with an !exclamation mark.  When a remote 
                party connects to you with the correct password,
                you'll be prompted to allow him in.  It is then also 
                impossible to gain access when your system is unattended.

v.3.20  97-05-30 Three new features:
              1. New escape sequence for VT100: Enq (0x05) will return 
		an ID string: "Inet VT100 version x.xx\r\n".
              2. The TCP/IP stack no longer acts as a router from an 
                interface back to the same interface.  This change will 
                limit the traffic generated on badly routed networks and 
                where multiple IP stacks run on the same physical interface.
                (The old feature is still available to those who need it:
                Use the command "route echo on").
              3. An experimental HTTP 1.0 server is included in INETL.
                Use "start httpserv" in INET.STU and set an environment 
                variable HTTP_DIR in your AUTOEXEC.BAT to indicate the 
                root HTTP directory containing INDEX.HTM.

v.3.21  97-06-12 Many changes and new features:
              1. The FTP server will use the paths relative 
                to the login directory for the CWD (CD) and 
                PWD commands. This conforms to the standard 
                used by most UNIX FTP servers.
                (Users normally can not do a CDUP (closer to 
                the root directory) unless they have directory 
                access. Users with access to directories above
                their login directory might be confused with 
                the way directories are displayed since INET 
                will to switch to paths relative to the root
                of the current disk. To have absolute paths 
                displayed, do a "CD C:\".)

              2. LPD and FTP uses the INETSPOOL or TEMP or TMP environment
                variables to find the temporary files directory needed
                for spool files and directory lists.

              3. The HTTP server (only in INETL.EXE) has some more 
                functionality. (RFC 1945)

              4. File handles: A new compiler will allow usage of 
                up to 60 file handles per program. The previous
                limitation was 20.  The problem only surfaced with 
                heavy FTP server activity.

              5. An HTTP client (only in INETL.EXE) can download files 
                using the http protocol.

                This feature can also be used to download many files
                from HTTP (WWW) servers automatically in batch mode.

                The command syntax is:
                        http get hostname filename option
                where "hostname" is the remote HTTP server,
                "filename" is the file to get (no wild cards) and
                the options are "w" for "wait" or "n" for "no-save".

                Multiple "http get" commands without the wait option
                will open multiple connections to transfer all the files
                simultaneously.  Use the wait option to force transfers 
                to be done sequentially.

                The "no-save" option is for testing purposes only.

                Use the "cd" command to change the local (destination) 
                directory.
                E.g.:   cd d:\download

                Sub-commands other than "get" have not yet been implemented.
                Depending on the remote server some commands like "read"
                will work mostly.

v.3.21  97-09-11 A typo in ICONFIG.DEF caused "too many }'s" error.
v.3.21  98-02-12 Add more example STart-Up (.STU) files with descriptions.
v.3.22  98-03-01 Support long passwords (characters more than 9 are ignored)
v.3.23  98-03-31 Invisible and underlined text in the VTxxx terminal.
                Some fixes to 3270 and printing to :0 
		Added support for remote printing.

		More of the SGR escape sequences are supported: 
			Esc [  8 m	Invisible on
			Esc [ 24 m	Underline off
			Esc [ 28 m	Invisible off

		Print-through and screen printing can be sent to a remote 
		machine running a socket print server.  Go to the UTE menu 
		(Alt M) and select "7 Change printer set-up string".
		Use the following syntax as the printer 0 name: 
			\\ip-address:port.  
		E.g.: With printer 0 called \\192.1.1.11:10 , UTE 
		will try to send print jobs to a socket print server 
		(like prntserv) running at 192.1.1.11 on port 10.

v.3.24  98-04-15 Option to ignore Num Lock commands for the VT terminal added.
		/k  Numeric Key Pad Lock option.
		Two escape sequences are being used to toggle the Num Lock
		status on a VTxxx terminal emulator: DECKPAM and DECKPNM.
		(See sec. 9.2.5. in the INET Network Manager's Guide.)
		If you do not like your application messing around with 
		your Num Lock setting and you can't fix your application
		that sends these sequences, you can instruct INET to just
		ignore them with the /k switch of the emulator command.

		In your .STU you must add or modify an emulator statement:

			emulator VTxxx /i=0 /k x:\INET\VTxxx.CNF

		To modify your default VT100 use:

			emulator VT100 /i=0 /k C:\INET\INETVT.CNF

		To create a new VT220 with keypad locked use:

			emulator VT220Key /t=vt220 /i=0 /k VT220.CNF

v.3.25  98-06-29 Support for DHCP added. (Consider as alpha software)
*** Notice ***
DHCP requires timers to be increased from 16 bits to 32 bits. 
External programs using the INET API may need recompilation.
v.3.26  98-07-02 Support for DHCP working.
                To activate DHCP, specify an IP address of 0.0.0.1
                All LAN interfaces specified when this IP address 
                is in use, will attempt to use DHCP to resolve the 
                IP address, the subnet mask, hostname, default 
                router and DNS server(s).

v.3.27  98-08-25 PPP now supported. (Consider as beta software)
v.3.28  98-09-05 PPP now supported and working!
v.3.29  98-09-18 API call GetPeer fixed.
v.3.30  98-10-08 132 column modes supported by VESA VGA cards are
                automatically detected.

98-11-11 More .STU examples for serial lines and modems.

v.3.31  99-01-08 Fixed LPD printing that was broken after v.3.24
		Added key-mapping for Shift-Up, Shift-Down and Tab.
		Smaller file sizes.
