Configuration File Keyword Reference - Terminal Emulation Settings

Items in this list configure terminal emulation settings for ssh and ssh2 command line sessions. These settings can be implemented by adding them manually to the Secure Shell configuration file, or by using the -o switch on the command line.

NOTE:These settings affect command line terminal sessions only; they have no affect on terminal sessions running in the Reflection user interface.

The configuration file is organized into sections, each identified by a Host keyword. Each section specifies settings to be used for all connections made using the specified host or SSH configuration scheme.

The configuration file consists of keywords followed by values. Configuration options may be separated by white space or by optional white space and exactly one equal sign (=). Keywords are case-insensitive and arguments are case-sensitive.

Any line starting with a number sign (#) is a comment. Any empty line is ignored.

Quotation marks are required around string arguments that include spaces. Terminal emulation keywords and arguments are not case-sensitive.

NOTE:Keywords for configuring Secure Shell connections are available in a separate list. See Configuration File Keyword Reference - Secure Shell Settings.
