NCSA Telnet 2.3b1
Please mail all questions and comments to:
telbug@ncsa.uiuc.edu
The following is a list of added features for NCSA Telnet 2.3b1 for the PC.
1) Telnet to any specified port:
This can be done in one of three ways: from inside of config.tel,
from the command line, or from the Alt-A menu inside of telnet.
NCSA Telnet uses port 23 (telnet server) as the default port. A port option
has been added to the keyword list allowing the default port to be changed
for a specified host. For example:
hostname=zaphod; port=25;
Placing the above line in config.tel will cause NCSA Telnet to connect to
port 25 (SMTP server) instead of port 23 (telnet server).
In order to achieve the same effect from the command line, specify the
hostname followed by a '#' followed by the port number.
c:\telnet> telnet zaphod#25
The Alt-A menu uses the same method as the command line.
2) Support for 43-line EGA mode and 50-line VGA mode.
The "video=" option in the config.tel file can be used to select
a 43- or 50-line screen. In order to get 43 lines of text, place the
following line in the config.tel, "video=ega43". Likewise, 50 lines of text
can be achieved by using, "video=vga50".
3) FTP now differentiates between filenames and directories.
4) Copy and Paste between sessions.
NCSA Telnet now provides the capability to copy data from one
session to another session. Copying can be done either by using the keyboard
or the mouse. To copy text using the keyboard:
Step 1: Enter scrollback mode by pressing the Scroll Lock key.
Step 2: Using the keyboard cursor keys, position the cursor on
the character that marks the beginning of the text to be copied and press the
space bar. The character will be highlighted.
Step 3: Move the cursor to the end of the text to be copied and press
the space bar. As the cursor moves, the selected text will be highlighted.
Step 4: Press Alt-C and the highlighted region will be copied into
a buffer.
If one of the endpoints needs to be moved, Shift-Space Bar will free the
endpoint nearest to the cursor and move it to the cursor's location. The
cursor and be moved to a new location if desired. Repeat Step 3 and 4 to
copy the text.
To copy text using the mouse:
Step 1: Enter scrollback mode by pressing the Scroll Lock key.
Step 2: Move the cursor to the beginning of the text to be copied.
Press and hold the left mouse button.
Step 3: Move the cursor to highlight the text region to be copied and
release the mouse button.
Step 4: Press Alt-C and the highlighted region will be copied into
a buffer.
If one of the endpoints needs to be moved, Shift-Left Mouse Button will free
the endpoint nearest to the cursor and change it to the cursor's location.
The cursor can be moved to a new location. Repeat Step 3 and 4 to copy
the text.
To retrieve the text from the buffer, exit out of scrollback mode and press
Alt-V. The text in the buffer will be sent to the current session. Caution
should be used, for the host will react exactly as if the text had been entered
from the keyboard. Currently, there is a 32K limit on the size of the copy
and paste buffer.
5) Drop into server mode after closing all sessions.
When NCSA Telnet is invoked with the -s command line option, it will
automatically enter the server mode when there are no open sessions.
6) Changes to the Parameter (Alt-P) menu.
The Parameter (Alt-P) menu has two new additions: options
to enable/disable ftp and rcp independently, and enable/disable Line wrapping.
A bug fix now allows one to cancel all changes by hitting the esc key.
7) New keystokes.
Alt-V: Will copy text from a buffer onto the current session.
Alt-C: In scrollback mode. Copies highlighted text into a buffer.
Alt-F: Formerly Alt-T. Will initiate an ftp call back to your PC.
Changed to make both the Macintosh and PC versions more similar.
8) New drivers.
NCSA_Telnet now supports the following drivers:

9) Keyboard mapper.
The keyboard mapper can be initialized by using the "keyfile=<filename>"
option in the config.tel file. This is a ascii file that contains keyboard
mapping information for NCSA Telnet. For additional information about the
keyboard mapping file format, please see the included file - 'keymap.txt'.
