IBM 3270 Emulation

SysReq Key Support

When the SysReq option in the Telnet Options dialog box 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. When communicating with the operating system the status line will display the symbol.

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

The Status Line

The last line in the window is used to display status information in the form of symbols and alphanumeric characters. A coloured line separates status information from the rest of the display. Information is displayed in any of nine regions within the status line as listed below.
