IBM 3270 Emulation Network Virtual Terminal Mode Network Virtual Terminal (NVT) mode allows the operator to communicate in ASCII format with a network gateway for routing, logon etc, before the full IBM terminal emulation protocol is established. The following symbol is displayed on the status line when in NVT mode: NVT mode displays an unformatted screen for data entry, allowing most of the keyboard functionality for local editing. However, when the Enter key is pressed, the line that the cursor is positioned on will be sent over Telnet as an ASCII string with CR/LF terminators. The cursor will then be positioned at the start of the next line. ASCII data received over Telnet will also be displayed at the current cursor position. A CR character will be actioned as a 'new line' character, causing the cursor to move to the start of the next line, scrolling the display if necessary. Once the appropriate details have been entered to establish an IBM host session (which may be automatic), the screen is cleared and switched into full IBM 3270 terminal emulation mode, as indicated by the following status line symbol: 302 Network Virtual Terminal Mode
