dtelnet: A Free Telnet Client for Windows 16/32/64

• For win32/64 help-file in chm format, from John G Zvonar
• IPv6 support (win32/64)

• New help-file from John G Zvonar
• Color selection in 'Terminal' menu
• terminal-type 'xterm-kbsH' became 'xterm-kbs8' (dtelnet.set)
• Minimal bugfixes

• Minimal bugfixes
• Using environment variable %USERPROFILE%, if %HOME% is not set
• new terminal types in dtelnet.set: xterm-kbs177, xterm-kbsH for special cases (see backspace.txt)

• Dtelnet's file extension changed from '.ts' to '.dtelnet_ses'
• From now, you can use NEW ENVIRONMENT feature (if your server supports it).
  add [EnvVars] section into your 'dtelnet.ini' or 'favourite.dtelnet_ses':
  

  [EnvVars]
  LC_CTYPE="hu_HU.ISO-8859-2"
  ORA_SDTZ="Europe/Budapest"

• New Connect/Reconnect menu command
• Most likely the last version for Windows16

• Help file added, thanks to Zvonar, JohnG
• Reorganized 'keypad application mode' settings in 'Connect' dialog. Most users should set both radio-buttons to 'Num'.
• For user without mouse: when connected, pressing and releasing both Alt's activates the menu
• New menu-command: Term/Mouse: you can assign function 'paste' to middle or right mouse-button.
• From now triple-click and quadruple-click are usable to select a (screen) line or a (logical) line. (The latter selects the wrapped lines, too.)
• In file dtelnet.set, two new terminal-types for linux-users: xterm-linuxbs and rxvt-linuxbs Read backspace.txt for details.

• Bugfix: Window-resize/maximize sometimes gave strange errors
• Bugfix: Cursor position was wrong in Midnight Commander when switched to alternate screen (Ctrl+O), also it wasn't 'vttest' compatible. Fixed.
• Other little fixes to make vttest happy (eg HPR = ESC[a)
  Note: after 'vttest', it's a good idea to execute 'reset' or printf '\033c'
• Another little bugfix in telnet-protocol handling

• VMS-friendly features: fixed/added ESC-sequences
• ScrollLock and Pause keys now act as 'Help' and 'Do'
• A new option to map editing keys VT-style (see below)
• Re-interpreted attributes again, try with the attached dtelnet.test.sh (with attrs argument)
• Option /A now accepts four colours (see below at option /A)
• From now, if you have a HOME environment variable, dtelnet will search config-files in %HOME%/Dtelnet directory

• Bugfix: Shift+F<num> should work now (test in Midnight Commander)

• Bugfix in Term/Emul (Windows 16 version only)
• Support for second mouse-wheel (to tell the truth I cannot test it),
  also support for "mouse button event" functionality (whatever it is)
• IMPORTANT Reorganized terminal types (dtelnet.set is changed, too); from now on, I'd suggest terminal-type konsole (or konsole-256color) for linux-servers, xterm (or xterm-256color) for AIX-servers. See file backspace.txt for more information.
   
  Also test these keys in mc/mcedit, they should work with the said terminal-types: Shift+Arrows, Ctrl+Up/Down, Ctrl+Home/End, Ctrl+PgUp/PgDn

• 'Secondary font' in 'Term/Font' menu: once if you set it, the change of the Primary Font won't corrupt the line-drawing characters. (Test with Midnight Commander.)
• With command-line option /A you can choose from 256 colors, eg /A 0xea-0xf8 is a nice, darkgrey on whitegrey combination.
• In file 'dtelnet.set', terminal type 'xterm' has been split into 'xterm-new' and 'xterm-old'. Test both to choose the better for your server.

• In Windows16, we are sending telnet.nop commands in every 65.535 secs to keep the connection alive; In Windows32/64 we use TCP_KEEPALIVE in every 10 minutes; (or the value from registry key: HKLM\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters\KeepAliveTime, if that is shorter than 10 minutes (NB: it is in millisec))
• Supporting 256 colors (sequences ESC[38;5;<colnum> and ESC[48;5;<colnum>); from now, the preferred terminal type is 'rxvt-256color' Test with: 'dtelnet.test.sh colors'
• This is the first version coming in three variants: Windows16/32/64

• From now on, you can map menu-commands to keys, too. Currently available: NewWindow and PrintScreen. Example:

    ; Map Ctrl+W to function 'NewWindow', Ctrl+P to function 'PrintScreen'
    ; Notice the lack of quotes.
    ;
    ; Ctrl,0x57 = NewWindow
    ; Ctrl,0x50 = PrintScreen

• Mouse wheel works again (but only in the 32-bit version) to scroll vertically; in Midnight Commander, test the wheel in itself, and together with Shift
• There were some problems with selection, attributes and anti-aliasing (especially ClearType) -- hopefully it's better now.
• The handling of colors has been changed: now 'blink' means intense background color, like 'bold' means intense foreground color.
• In the Font-selection menu you can choose bold font now -- it might or might not work for you (check with Midnight Commander).
• More function keys (26, 24 editable in the GUI) -- for special uses. Remember: F11=Shift+F1, F22=Shift+F12
• A test script (dtelnet.test.sh), to test colors, alternate buffer, scrolling etc.
• Underline support, it may or may not work depending on font/size, test from unix:

  tput smul; echo underlined; tput rmul

• Option -I<inifile> works again, but you have to use quotes if there are backslashes in the pathname:

  -I'C:\HOME\USERNAME\DTELNET.INI'

• Support for key-mapping – no GUI though, you have to edit your dtelnet.ini or *.ts file manually. Read the attached keymap.txt for details. A little example:

  ; map Alt+M to "mc\r", Alt+Shift+M to "mcedit ":
  Alt,Shift-,0x4d = "mc\r"
  Alt,Shift+,0x4d = "mcedit "
  

• Help file dropped — it's been unmaintaned since the past millenium.

• Now Shift-key undoes 'mouse reporting', so in mc[edit] you can select text parts with Shift+mouse.
• Command-line attribute /A has changed: now 'color' means dark-color, 'Color' means light-color (compare '/A black-white' and '/A black-White').
• When starting, we try to keep the window within the screen;)

If you replace +X with -X, the right edge of the window will be placed X pixels from the right of the screen. Likewise, a -Y will place the window with the bottom edge Y pixels from the bottom of the screen.
