-
-			<li>*Boot log and debug messages* are available on pin *GPIO2* (P2) at 115200\,baud, 1 stop bit, no parity.
-				Those messages may be disabled through compile flags.
-
-			<li>*Loopback test*: Connect the Rx and Tx pins with a piece of wire. Anything you type in the browser should
-				appear on the screen. Set _Parser Timeout = 0_ in <a href="<?= url('cfg_term') ?>">Terminal Settings</a>
-				to be able to manually enter escape sequences.
-
-			<li>There is very little RAM available to the webserver, and it can support at most 4 connections at the same time.
-				Each terminal session (open window with the terminal screen) uses one persistent connection for screen updates.
-				*Avoid leaving unused windows open*, or either the RAM or connections may be exhausted.
-
-			<li>*For best performance*, use the module in Client mode (connected to external network) and minimize the number
-				of simultaneous connections. Enabling AP consumes extra RAM because the DHCP server and Captive Portal
-				DNS server are started.
-
-			<li>In AP mode, *check that the WiFi channel used is clear*; interference may cause flaky connection.
-				A good mobile app to use for this is
-				<a href="https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer">WiFi Analyzer (Google Play)</a>.
-				Adjust the hotspot strength and range using the _Tx Power setting_.
-
-			<li>Hold the BOOT button (GPIO0 to GND) for ~1 second to force enable AP. Hold it for ~6 seconds to restore default settings.
-				(This is indicated by the blue LED rapidly flashing). Default settings can be overwritten in the

-
-		<p>
-			The blue buttons under the screen send ASCII codes 1, 2, 3, 4, 5, which incidentally
-			correspond to _Ctrl+A,B,C,D,E_. This choice was made to make button press parsing as simple as possible.
-		</p>
-
-		<h3>Mouse</h3>
-
-		<p>
-			ESPTerm implements standard mouse tracking modes based on Xterm. Mouse tracking can be used to implement
-			powerful user interactions such as on-screen buttons, draggable sliders or dials, menus etc. ESPTerm's
-			mouse tracking was tested using VTTest and should be compatible with all terminal applications
-			that request mouse tracking.
-		</p>
-
-		<p>
-			Mouse can be tracked in different ways; some are easier to parse, others more powerful. The coordinates
-			can also be encoded in different ways. All mouse tracking options are set using option commands:
-			`CSI ? _n_ h` to enable, `CSI ? _n_ l` to disable option _n_.
-		</p>
-
-		<h4>Mouse Tracking Modes</h4>
-
-		<p>
-			All tracking modes produce three numbers which are then encoded and send to the application.
-			First is the _event number_ N, then the _X and Y coordinates_, 1-based.
-		</p>
-
-		<p>
-			Mouse buttons are numbered: 1=left, 2=middle, 3=right.
-			Wheel works as two buttons (4 and 5) which generate only press events (no release).
-		</p>

-		<div class="tscroll">
-		<table class="nomen">
-			<thead><tr><th>Option</th><th>Name</th><th>Description</th></tr></thead>
-			<tr>
-				<td>`9`</td>
-				<td>*X10~mode*</td>
-				<td>
-					This is the most basic tracking mode, in which <b>only button presses</b> are reported.
-					N = button - 1: (0 left, 1 middle, 2 right, 3, 4 wheel).
-				</td>
-			</tr>
-			<tr>
-				<td>`1000`</td>
-				<td>*Normal~mode*</td>
-				<td>
-					In Normal mode, both button presses and releases are reported.
-					The lower two bits of N indicate the button pressed:
-					`00b` (0) left, `01b` (1) middle, `10b` (2) right, `11b` (3) button release.
-					Wheel buttons are reported as 0 and 1 with added 64 (e.g. 64 and 65).
-					Normal mode also supports tracking of modifier keys, which are added to N as bit masks:
-					4=_Shift_, 8=_Meta/Alt_, 16=_Control/Cmd_. Example: middle button with _Shift_ = 1 + 4 = `101b` (5).
-				</td>
-			</tr>
-			<tr>
-				<td>`1002`</td>
-				<td>*Button-Event tracking*</td>
-				<td>
-					This is similar to Normal mode (`1000`), but mouse motion with a button held is also reported.
-					A motion event is generated when the mouse cursor moves between screen character cells.
-					A motion event has the same N as a press event, but 32 is added.
-					For example, drag-drop event with the middle button will produce N = 1 (press), 33 (dragging) and 3 (release).
-				</td>
-			</tr>
-			<tr>
-				<td>`1003`</td>
-				<td>*Any-Event tracking*</td>
-				<td>
-					This mode is almost identical to Button Event tracking (1002), but motion events
-					are sent even when no mouse buttons are held. This could be used to draw on-screen mouse cursor, for example.
-					Motion events with no buttons will use N = 32 + _11b_ (35).
-				</td>
-			</tr>
-			<tr>
-				<td>`1004`</td>
-				<td>*Focus~tracking*</td>
-				<td>
-					Focus tracking is a separate function from the other mouse tracking modes, therefore they can be enabled together.
-					Focus tracking reports when the terminal window (in Xterm) gets or loses focus, or in ESPTerm's case, when any
-					user is connected. This can be used to pause/resume a game or on-screen animations.
-					Focus tracking mode sends `CSI I` when the terminal receives, and `CSI O` when it loses focus.

-					In this mode, a mouse report has the format `CSI M _n_ _x_ _y_`,
-					where _n_, _x_ and _y_ are characters with ASCII value = 32 (space) + the respective number, e.g.
-					0 becomes 32 (space), 1 becomes 33 (!). The reason for adding 32 is to avoid producing control characters.
-					Example: `\e[M !!` - left button press at coordinates 1,1 when using X10 mode.

+		<h3>Action buttons</h3>
+
+		<p>
+			The blue buttons under the screen send ASCII codes 1, 2, 3, 4, 5, which incidentally
+			correspond to _Ctrl+A,B,C,D,E_. This choice was made to make button press parsing as simple as possible.
+		</p>
+
+		<h3>Mouse</h3>
+
+		<p>
+			ESPTerm implements standard mouse tracking modes based on Xterm. Mouse tracking can be used to implement
+			powerful user interactions such as on-screen buttons, draggable sliders or dials, menus etc. ESPTerm's
+			mouse tracking was tested using VTTest and should be compatible with all terminal applications
+			that request mouse tracking.
+		</p>
+
+		<p>
+			Mouse can be tracked in different ways; some are easier to parse, others more powerful. The coordinates
+			can also be encoded in different ways. All mouse tracking options are set using option commands:
+			`CSI ? _n_ h` to enable, `CSI ? _n_ l` to disable option _n_.
+		</p>
+
+		<h4>Mouse Tracking Modes</h4>
+
+		<p>
+			All tracking modes produce three numbers which are then encoded and send to the application.
+			First is the _event number_ N, then the _X and Y coordinates_, 1-based.
+		</p>
+
+		<p>
+			Mouse buttons are numbered: 1=left, 2=middle, 3=right.
+			Wheel works as two buttons (4 and 5) which generate only press events (no release).
+		</p>
+
+		<div class="tscroll">
+			<table class="nomen">
+				<thead><tr><th>Option</th><th>Name</th><th>Description</th></tr></thead>
+				<tr>
+					<td>`9`</td>
+					<td>*X10~mode*</td>
+					<td>
+						This is the most basic tracking mode, in which <b>only button presses</b> are reported.
+						N = button - 1: (0 left, 1 middle, 2 right, 3, 4 wheel).
+					</td>
+				</tr>
+				<tr>
+					<td>`1000`</td>
+					<td>*Normal~mode*</td>
+					<td>
+						In Normal mode, both button presses and releases are reported.
+						The lower two bits of N indicate the button pressed:
+						`00b` (0) left, `01b` (1) middle, `10b` (2) right, `11b` (3) button release.
+						Wheel buttons are reported as 0 and 1 with added 64 (e.g. 64 and 65).
+						Normal mode also supports tracking of modifier keys, which are added to N as bit masks:
+						4=_Shift_, 8=_Meta/Alt_, 16=_Control/Cmd_. Example: middle button with _Shift_ = 1 + 4 = `101b` (5).
+					</td>
+				</tr>
+				<tr>
+					<td>`1002`</td>
+					<td>*Button-Event tracking*</td>
+					<td>
+						This is similar to Normal mode (`1000`), but mouse motion with a button held is also reported.
+						A motion event is generated when the mouse cursor moves between screen character cells.
+						A motion event has the same N as a press event, but 32 is added.
+						For example, drag-drop event with the middle button will produce N = 1 (press), 33 (dragging) and 3 (release).
+					</td>
+				</tr>
+				<tr>
+					<td>`1003`</td>
+					<td>*Any-Event tracking*</td>
+					<td>
+						This mode is almost identical to Button Event tracking (1002), but motion events
+						are sent even when no mouse buttons are held. This could be used to draw on-screen mouse cursor, for example.
+						Motion events with no buttons will use N = 32 + _11b_ (35).
+					</td>
+				</tr>
+				<tr>
+					<td>`1004`</td>
+					<td>*Focus~tracking*</td>
+					<td>
+						Focus tracking is a separate function from the other mouse tracking modes, therefore they can be enabled together.
+						Focus tracking reports when the terminal window (in Xterm) gets or loses focus, or in ESPTerm's case, when any
+						user is connected. This can be used to pause/resume a game or on-screen animations.
+						Focus tracking mode sends `CSI I` when the terminal receives, and `CSI O` when it loses focus.

+					<td>*Normal~encoding*</td>
+					<td>
+						This is the default encoding scheme used when no other option is selected.
+						In this mode, a mouse report has the format `CSI M _n_ _x_ _y_`,
+						where _n_, _x_ and _y_ are characters with ASCII value = 32 (space) + the respective number, e.g.
+						0 becomes 32 (space), 1 becomes 33 (!). The reason for adding 32 is to avoid producing control characters.
+						Example: `\e[M !!` - left button press at coordinates 1,1 when using X10 mode.
+					</td>
+				</tr>
+				<tr>
+					<td>`1005`</td>
+					<td>*UTF-8~encoding*</td>
+					<td>
+						This scheme should encode each of the numbers as a UTF-8 code point, expanding the maximum possible value.
+						Since ESPTerm's screen size is limited and this has no practical benefit, this serves simply as an alias
+						to the normal scheme.
+					</td>
+				</tr>
+				<tr>
+					<td>`1006`</td>
+					<td>*SGR~encoding*</td>
+					<td>
+						In SGR encoding, the response looks like a SGR sequence with the three numbers as semicolon-separated
+						ASCII values. In this case 32 is not added like in the Normal and UTF-8 schemes, because
+						it would serve nor purpose here. Also, button release is not reported as 11b,
+						but using the normal button code while changing the final SGR character: `M` for button press
+						and `m` for button release. Example: `\e[2;80;24m` - the right button was released
+						at row 80, column 24.
+					</td>
+				</tr>
+				<tr>
+					<td>`1015`</td>
+					<td>*URXVT~encoding*</td>
+					<td>
+						This is similar to SGR encoding, but the final character is always `M` and the numbers are
+						like in the Normal scheme, with 32 added. This scheme has no real advantage over the previous schemes and
+						was added solely for completeness.

+				Each terminal session (open window with the terminal screen) uses one persistent connection for screen updates.
+				*Avoid leaving unused windows open*, or either the RAM or connections may be exhausted.
+
+			<li>*For best performance*, use the module in Client mode (connected to external network) and minimize the number
+				of simultaneous connections. Enabling AP consumes extra RAM because the DHCP server and Captive Portal
+				DNS server are started.
+
+			<li>In AP mode, *check that the WiFi channel used is clear*; interference may cause flaky connection.
+				A good mobile app to use for this is
+				<a href="https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer">WiFi Analyzer (Google Play)</a>.
+				Adjust the hotspot strength and range using the _Tx Power setting_.
+
+			<li>Hold the BOOT button (GPIO0 to GND) for ~1 second to force enable AP. Hold it for ~6 seconds to restore default settings.
