\section{The Set-Up Screens}
The Set-Up screens imitate the same functions on a real DEC VT100 terminal.
Use \LKeyF{1} to toggle the help display which shows all keys. \\

\subsection{Set-Up A}
This page shows the tab stops and offers to toggle \textbf{80/132 columns} text display and also switching between
\textbf{online} and \textbf{local mode}.
This page shows the tab stops at the bottom of the screen.
In \textbf{online mode}, the terminal is connected to the computer via the serial port.\\
In \textbf{local mode}, the terminal can be used to connect directly to the modem using the \textit{Quick Settings menu} (see \vref{quicksettings}).

\item Use keys \LKey{7} and \LKey{8} to set the baudrate used on the terminal serial port, it is shown in the lower right.
\item US/UK switch will replace \# with \pounds
\item The Ansi/VT52 bit is for VT100 compatibility, as it reacts to \texttt{ESC[?2l} (start VT52 mode) and \texttt{ESC<} (return to ANSI mode,
ie. ANSI/VT100 personality). Changing the personality to VT52 disables this bit, all other wil enable it.
\item The bits for \textbf{bold} text are applied to text with the attribute \texttt{ESC[1m}.
\item \textit{Home on Erase} makes the cursor go home (\texttt{ESC [H}) on a clear screen request (\texttt{ESC[2J}), just as MS-DOS \texttt{ANSI.SYS} works.
\item \textit{ANSI.SYS Compliance} makes the cursor go home (\texttt{ESC[H}) on a clear screen request (\texttt{ESC[2J}),
and makes some of the lower ASCII characters (between 0x00-0x1F) visible.
