Menu Reference

Crescat offers options to customize terminal sessions, for those who need it. Customization can be done at login time, by pressing the disclosure button on the login panel:

Customization is also available for open sessions using the “Session Settings...” command in the File menu, and for saved host/user combinations using the “Manage Host/User Defaults” command.

The available options are:

Rows

The number of lines of text the terminal displays.

Columns

The number of characters each the terminal displays in each line.

Port

The TCP port on which the connection is to be made. Unless you know you are doing something special, leave this as 22.

Text Color

The color in which text appears in the terminal. Make sure this contrasts with the background color.

Background Color

The color of the terminal contents, on which the text appears. Make sure to pick a color that contrasts with the text color.

Cursor Color

The color of the terminal's cursor (not to be confused with the mouse cursor). Again, this should contrast with the background color.

Cursor Style

Whether the cursor should be the full size of a character, half the size, or just an underline — a matter of taste.

Delete Key

What character code the “delete” key in the upper-right corner of the keyboard sends. Most hosts expect the ASCII Delete character, but a few want the ASCII backspace.

SSH Version

What version of the SSH protocol Crescat should use. Usually it's best to try to use version 2, and automatically fall back to 1 if that doesn't work (shown in the control as “Try 2, then 1”), but specific hosts may require another strategy. Older hosts, in particular, respond only to SSH version 1.

Cipher

The SSH protocol offers a choice of ciphers used to protect the data that passes between your terminal and the remote host. The usual choice is Triple-DES. Single DES and the Blowfish cipher are also available. Single DES should be used only with hosts that support nothing else, as it is regarded as cryptographically insecure.

Compress All Data

SSH can optionally compress the encrypted data that passes between your terminal and the remote host. On slower communications lines (such as dialup) this can result in quicker performance.
