VT3270
What is VT3270?
Like Telnet, VT3270 enables access to programs running on remote hosts. Unlike Telnet,
VT3270 provides the means to access 3270 programs running on IBM mainframes.
VT3270 enables the UCT-L to function as though it were a 3279 mod 2, mod 3, mod 4,
or mod 5 terminal. Unlike Telnet, VT3270 can manipulate the entire screen image,
fields and function keys, in a way identical to a 3270 terminal. VT3270 provides the
following standard features:
• Window Menus – The window menus offer simplicity and ease of use for all setup
functions.
• Color Display – The color monitor is programmable in seven colors.
• Switchable Screen Formats – VT3270 supports four (4) screen sizes that can be
selected from setup menus. The server to which the VT3270 client attaches must be
configured to support the screen size used. Check with your system administrator.
• Mono/DualCase Mode – Allows characters to be displayed as all uppercase
characters or as upper- and lowercase characters.
• Mark Unprotected Field Indicator – The 1480 CUT Emulator can be requested
to mark unprotected fields with a special character.
• Row/Column Indicator – Displays the current cursor location on the operator
status row.
• Numeric Lock – Allows a field to be defined to accept only numeric characters and
the Period, Minus, and Dup keys. The comma may be substituted for the period on
some international keyboards.
• Multiple Sessions – A maximum of 10 sessions can be accessed with this emulator.
