The telnet environment on workstations offers in addition to the line-by-line mode the emulation of a DEC VT100 terminal or a full screen IBM 3270 terminal. To start the telnet 3270 emulation, enter
3270 cernvm
which connects directly to the CERNVM system.
With this product you can have up to 46 lines on your screen or alternatively a wide 132 character display depending on the original size of the window. The disadvantages are the lack of colour support and the lack of provision for transcript pad or window copying.
The maximum screen size will be used, depending on the lines/columns values of the screen from which the session is initiated. 3270 has an online help facility accessible via <ctrl>-e or the "Help" key. One particularly useful option is to display the keyboard mapping which the program thinks that you have and a second displays the function corresponding to a key that you select. The 3270 keyboard mapping is determined by the value of the KEYMAP environment variable or, if that is not defined, by the TERM variable. If you wish to set up your own keymap, you should set the variable MAP3270 to the absolute pathname of the file containing your desired keymap, which you would normally create by modifying the file /usr/local/lib/map3270. For more information, see the man page.
