Terminal / Emulation

This category only appears if VanDyke Software's SecureCRT® 5.0 (or newer) is also installed.

The Emulation category of the Session Options dialog allows you to customize your terminal emulation for a session . Terminal keyboard emulation settings are defined by a keymap file. SecureCRT includes several built-in keymap files: VT100, VT220, Linux, SCO ANSI, Custom, and Default. The Default keymap file defines an emulation most similar to the PC keyboard, but also provides mappings for the keys F1-F4. SecureCRT will automatically choose a keyboard emulation based on the Terminal emulation that you select but you can change this selection using the Select an alternate keyboard emulation option described below.

Emulation group

This group contains general emulation controls.

Terminal

Select the terminal type that you want to emulate. SecureCRT supports ANSI, Linux, SCO ANSI, TN3270, VShell, VT100, VT102, VT220, WYSE50, WYSE60, and Xterm terminal emulation.

ANSI Color

Check this option to use the ANSI color palette defined in the Terminal/Appearance/ANSI Color category of the Global Options dialog.

Use color scheme

When ANSI color is selected, check this option to honor the color scheme defined in the Global Options/Terminal/Appearance/Color Scheme dialog. Otherwise, the default ANSI foreground and background colors will be used.

Select an alternate keyboard emulation

SecureCRT automatically chooses a keyboard emulation (or "keymap") to use based on the Terminal emulation described above. To select a different keymap, check this option and select from the list of keymaps, or use the Browse button to display the Open dialog and select the keymap you want.

For more information on customizing the keyboard for your needs, see Overview of Keymaps" in the SecureCRT Help system.
