<p>Bright foreground can also be set using the "bold" attribute 1 (eg. <code>\e[31;1m</code>). For more details, see the ANSI code reference below.</p>

<h2>User Input</h2>
<p>
All the user types on their keyboard is sent as-is to the UART, including ESC, ANSI sequences for arrow keys and CR-LF for Enter.
The input is limited to ASCII codes 32-126, backspace 8 and tab 9.
</p>
<p>The buttons under the screen send ASCII codes 1, 2, 3, 4, 5.</p>
<p>
<b>Mouse input</b> (click/tap) is sent as <code>\e?;?M</code> with row;column. You can use this for on-screen buttons, menu navigation etc.
<i>Please note this is a custom sequence, not supported by PuTTY or other terminals.</i>
</p>
</div>
<divclass="Box">
<h2>Supported ANSI Escape Sequences</h2>
<p>Sequences are started by ASCII code 27 (ESC, <code>\e</code>, <code>\x1b</code>, <code>\033</code>)</p>
<p>Instead of <code>\a</code> (BELL, ASCII 7) in the commands, you can use `\e\` (ESC + backslash). It's the Text Separator code.</p>
<h3>Text Attributes</h3>
<p>
All text attributes are set using <code>\e[...m</code> where the dots are numbers separated by semicolons.
You can combine up to 3 attributes in a single command.
