These <em>terminal parameters</em> are mostly a convenient way of storage for terminal-local variables, but some terminal parameters have a special meaning. </p> <p>This section describes functions to read and change the parameter values of a terminal. They all accept as their argument either a terminal or a frame; the latter means use that frame’s terminal. An argument of <code>nil</code> means the selected frame’s terminal. </p> <dl> <dt id="terminal-parameters">Function: <strong>terminal-parameters</strong> <em>&optional terminal</em> +</dt> <dd><p>This function returns an alist listing all the parameters of <var>terminal</var> and their values. </p></dd> +</dl> <dl> <dt id="terminal-parameter">Function: <strong>terminal-parameter</strong> <em>terminal parameter</em> +</dt> <dd><p>This function returns the value of the parameter <var>parameter</var> (a symbol) of <var>terminal</var>.
