SysReq Key Support

When the SysReq option in the Telnet Options dialog is selected, the key mapped with the SysReq function enables you to toggle the display and keyboard entries between the host operating system and the application. This enables you to switch to the operating system and issue a LOGOFF command.

The status line will display the following symbol when communicating with the operating system:

NOTE: Not all TN3270E servers provide full support of the SysReq key.

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
