NOTICE:
   CUTCP/CUTE is a revised version of Clarkson's NCSA 2.2C,2.2D and 2.2TN

   The name has been changed to reduce confusion between NCSA's product, and
   Clarkson's version. Be aware that the current work is based on NCSA Telnet
   version 2.2.

   You may notice that the version numbers are becoming more complicated.
   Digest as follows:

	2.2D/MSC-B
         ^ ^  ^  ^
  	 | |  |  |---  Release number
	 | |  |------  Compiler/Library  (TC,MSC or NFS 'PC-NFS')
         | |---------  D for Telnet/rlogin   TN for Telnet/Rlogin and 3270
         |-----------  Major.minor program version.

  *Please refer to the exact version when reporting bugs, etc. 

   If you have problems installing or operating this program, 
   I beg you to seek local assistance before writing, calling, 
   faxing or mailing questions to me. 

   Due to workload, I have begun turning away some phone calls from end-users.
   You should contact your local network support person. Have THAT person
   call me for assistance if they have to. There's nothing more annoying 
   trying to explain what a packet driver is to a professor who could have
   asked his local networking support person.


   I encourage you to use the cutcp mailing list for general questions
   about this package. I also encourage everyone who can answer these questions
   to respond to the poster.

   Genuine bugs (not configuration problems) are welcome! Please send them
   to   cutcp-bugs@omnigate.clarkson.edu

   This release ('D') consists of several major bug fixes, some obscure
   (and some useful) enhancements. Please see the Revisions list below,
   and consult the sample config.tel file included. Note that the REV -D
   release does not include the MSC only version.

Revisions, Bug fixes, Improvements  (reverse chronological order)

Release-D   11/12/90, adds, fixes or changes:
	0. This release is NOT OVERLAID. You may install the binaries as
	   execute only on your file server (if desired).
	1. Autovideo detection no-longer clobbers the built-in keymap
	   video=auto is safe.
	2. ASCII FTP transfers to your PC using TN3270 or telbin has been fixed.
	   Neither program truncates files.
	3. The built-in ftp server no longer gives Error 451 on directories 
  	   that contain a lot of files.
	4. Logout while in tek mode will now reset the screen to text mode.
	5. TN_DUP (tn3270) has been re-defined as ALT-BACKSPACE to avoid
	   conflict with Script_Spawn/Kill.
	6. New script commands (see readme.scr)
	     setsname - sets the current session name on the statline
	     keymap - loads a new keymap for the current session or all sessions.
	7. FTPBIN no longer overwrites the screen during userid prompt.
	8. Domain name lookups appear to be fixed. The domainslist 
	   no longer advances the domain suffix when a timeout occurs.
	9. VTwrap mode is now settable from the ALT-P menu.
	10. Network slowdowns caused by escaping to Dos for long periods of
	    time while USING A PACKET DRIVER (only) appears to be fixed.
	11. Loopback support has been added. Telnet to 127.0.0.1 results in
	    a loopback window that can be used to fool cutcp.
	12. All key definitions are now redefinable from WITHIN a session.
	    ie: you can redefine ALTF3, ALT-A etc. study default.tbl for
	    examples and a listing of the current defaults. 
	    (You may NOT redefine system macros (ALT-A, etc) in microtn
	     because microtn does not have these functions).

	    caveats:
		a. You can NOT redefine the CONSOLE key definitions for
	   	   ESC, ALT-A, ALT-Z, ALT-V and ALT-F3. Ie. when Cute is 
		   started in server mode, these basic keys are not 
		   redefinable until at least one session is open. You can, 
		   however, use the loopback address to open a 'dummy' 
		   connection.

		b. The SYS_HELP screen (ALT-H by default) will not change
		   to reflect your new keyboard definitions. It shows only
		   the default hard-coded values.

		   You can, however, bind a script to the ALT-H key, have
		   that script open a loopback window and display your own
		   personal help screen.

		   see sample3.scr, sample3.tbl and sample3.def for an example.

		c. Don't box yourself into a corner. Its possible to undefine
		   ALTF3 and ALT-X. If you then open a loopback window there
		   will be no way to quit without rebooting. (which might
		   be a helpful feature.)...

	13.  A possible infinite loop in tn3270 (ERASE_ALL_UNPROTECTED)
	     has been removed.

Release-C   9/10/90, adds, fixes or changes:
	1. User configurable keymaps for both 3278 and vt100 sessions.
	2. Screens up to 132 x 61 lines, and support for 3278-5,
	   If you  have EGA or VGA utilities for wide or tall screens, 
	   CUTE will read the current screen dimensions from Bios. If you
 	   don't have such a program, I suggest UltraVision from 
	   Personics (508)897-1575.
	3. Rshell Client  (ALT-V)
	4. Topview/Desqview screen buffer detection (not tested)
	5. FTP to PC detects disk full.
	6. LNM VT100 escape SET/RESET sequence <ESC>[20h and <ESC>[20l
	   for automatic <CR> after <NL> (default is off, used by Rshell)
	7. Machine specific flags option sets 3270 mode and transparent data
	   destination.
	8. Rlogin now supports destination userid specification.
	9. VGA support for 640 x 480 tek emulation.
	10. Do terminal type loop fixed.
	11. NOARPME config.tel option inhibits arp for self at startup.
	12. 43 and 35 line mode on VGAs now fill screen. 
	13. Destination port number may be specified on command line.
	    ( tn3270 "myhost 25")
	14. Margin bell at column 72.
	15. Bios=maybe mode for visually impaired.
	16. Visual bell for hearing impaired.
	17. Nested config.tel files using include=option.
	18. DOS Environment config.tel options using  $CUTCPnn=
	19. Command line config.tel options using -e "myip=bootp" etc.
	20. Incoming FTP warning bell for visually impaired.
	21. Tek emulation supports colors 0-F on EGA and VGA.
	22. FM and DUP work in tn3270.
	23. Sounds= command in config.tel allows user tailored sounds.
	24. The NFS version now includes FTPBIN, but its still flaky.
	25. Script command files for 'auto dialing'.
	26. Other stuff that I've fixed but forgot to write down.
	27. TurboC VROOM swapping to EMS or EXTENDED Memory (code only).
  	    Use -me or -mx (tn3270 ? gives you more help)
	28. ^H sends ascii(8) regardless of erase= setting (for emacs).

Release-A   2/13/90, adds, fixes or changes:

	1. Echo Negotiation improved. Default telnet echo is now local. 
	2. Binary mode now works correctly.
	3. Compile time option for 'PACKET DRIVERS ONLY' saves 12K of RAM.
	4. Throughput measurement test reachable via ALT-P/terminal type,
           or set vtwrap=T in config.tel file.
	5. Domain name timeout handling has been improved, but is still slightly
	   broken.
	6. Maximum window size is now 61 lines (telbin -l 61 if you can read it).
	7. TSO systems are now handled, users can switch from linemode to 3270
 	   emulation and back multiple times.
	8. BootP now requests RFC1048 mode in the vendor field.
	9. Van Jacobson TCP header compression enabled on slip lines if
	   config.tel entry  has   vjc=yes
	10. Clock is configurable, clock=none, clock=12, clock=24 followed
	    by optional :timezone (for MSC version) or use dos set TZ=EST5EDT
	11. Rlogin! (yeah) Use ALT-Z to rlogin, or specify port 513
	12. Be sure to set your userid using   myname=  in config.tel
	13. Print Through mode (ESC[5i) now switches modes immediately such
	    that escape sequences won't appear in capture file.
	14. Screen updating is faster.
	15. Capture file may be written in text (default) or binary mode.
	    capfile="filename,b"  or ="filename,t", also settable using ALT-P
	16. FTP Server Fixes (in Telbin or TN3270 only)
		A. Now remembers starting directory, restores on quit.
		B. Dir command now lists bytes available.
		C. LS command now does not return directories
		D. MKDIR, RMDIR and DELE now supported.
		E. ALT-T doesn't put -n on command line.
		F. files PUT to PC are truncated as required.

	17. TCP handling improvements
		A. Nagle 
		B. Slow-start and congestion avoidance.
		C. handles remote sending 0 window.
	18. VT100 graphics characters handled better, now in scrollback buffer.
	19. ALT-D (screendump) works in scrollback mode.
	20. 3270 will autoskip fields seperated by a single space. (i think)
	21. PC-NFS support.. ALPHA mode now.. tn3270.exe and telbin.exe seem
	    to work, but due to severe limitations in the NFS toolkit, you can
	    only have three active sessions, plus ftp, plus nameserver lookup.
            Ftpbin.exe is totally broke, so its not in the package yet.
