+### Region Examples
+
+**Example 1: Using F Flag with Named Public Region**
+```
+region load
+#Europe F
+<blank line to end region load>
+region save
+```
+
+**Explanation:**
+- Creates a region named `#Europe` with flooding enabled
+- Packets from this region will be flooded to other nodes
+
+---
+
+**Example 2: Using Wildcard with F Flag**
+```
+region load 
+* F
+<blank line to end region load>
+region save
+```
+
+**Explanation:**
+- Creates a wildcard region `*` with flooding enabled
+- Enables flooding for all regions automatically
+- Applies only to packets without transport codes
+
+---
+
+**Example 3: Using Wildcard Without F Flag**
+```
+region load 
+*
+<blank line to end region load>
+region save
+```
+**Explanation:**
+- Creates a wildcard region `*` without flooding
+- This region exists but doesn't affect packet distribution
+- Used as a default/empty region
+
+---
+
+**Example 4: Nested Public Region with F Flag**
+```
+region load 
+#Europe F
+  #UK
+    #London
+    #Manchester
+  #France
+    #Paris
+    #Lyon
+<blank line to end region load>
+region save
+```
+
+**Explanation:**
+- Creates `#Europe` region with flooding enabled
+- Adds nested child regions (`#UK`, `#France`)
+- All nested regions inherit the flooding flag from parent
+
+---
+
+**Example 5: Wildcard with Nested Public Regions**
+```
+region load 
+* F
+  #NorthAmerica
+    #USA
+      #NewYork
+      #California

+# MeshCore KISS Modem Protocol
+
+Standard KISS TNC firmware for MeshCore LoRa radios. Compatible with any KISS client (Direwolf, APRSdroid, YAAC, etc.) for sending and receiving raw packets. MeshCore-specific extensions (cryptography, radio configuration, telemetry) are available through the standard SetHardware (0x06) command.
+
+## Serial Configuration
+
+115200 baud, 8N1, no flow control.
+
+## Frame Format
+
+Standard KISS framing per the KA9Q/K3MC specification.
+
+| Byte | Name | Description |
+|------|------|-------------|
+| `0xC0` | FEND | Frame delimiter |
+| `0xDB` | FESC | Escape character |
+| `0xDC` | TFEND | Escaped FEND (FESC + TFEND = 0xC0) |
+| `0xDD` | TFESC | Escaped FESC (FESC + TFESC = 0xDB) |
+
+```
+┌──────┬───────────┬──────────────┬──────┐
+│ FEND │ Type Byte │ Data (escaped)│ FEND │
+│ 0xC0 │  1 byte   │ 0-510 bytes  │ 0xC0 │
+└──────┴───────────┴──────────────┴──────┘
+```
+
+### Type Byte
+
+The type byte is split into two nibbles:
+
+| Bits | Field | Description |
+|------|-------|-------------|
+| 7-4 | Port | Port number (0 for single-port TNC) |
+| 3-0 | Command | Command number |
+
+Maximum unescaped frame size: 512 bytes.
+
+## Standard KISS Commands
+
+### Host to TNC
+
+| Command | Value | Data | Description |
+|---------|-------|------|-------------|
+| Data | `0x00` | Raw packet | Queue packet for transmission |
+| TXDELAY | `0x01` | Delay (1 byte) | Transmitter keyup delay in 10ms units (default: 50 = 500ms) |
+| Persistence | `0x02` | P (1 byte) | CSMA persistence parameter 0-255 (default: 63) |
+| SlotTime | `0x03` | Interval (1 byte) | CSMA slot interval in 10ms units (default: 10 = 100ms) |
+| TXtail | `0x04` | Delay (1 byte) | Post-TX hold time in 10ms units (default: 0) |
+| FullDuplex | `0x05` | Mode (1 byte) | 0 = half duplex, nonzero = full duplex (default: 0) |
+| SetHardware | `0x06` | Sub-command + data | MeshCore extensions (see below) |
+| Return | `0xFF` | - | Exit KISS mode (no-op) |
+
+### TNC to Host
+
+| Type | Value | Data | Description |
+|------|-------|------|-------------|
+| Data | `0x00` | Raw packet | Received packet from radio |
+
+Data frames carry raw packet data only, with no metadata prepended. The Data command payload is limited to 255 bytes to match the MeshCore maximum transmission unit (MAX_TRANS_UNIT); frames larger than 255 bytes are silently dropped. The KISS specification recommends at least 1024 bytes for general-purpose TNCs; this modem is intended for MeshCore packets only, whose protocol MTU is 255 bytes.
+
+### CSMA Behavior
+
+The TNC implements p-persistent CSMA for half-duplex operation:
+
+1. When a packet is queued, monitor carrier detect
+2. When the channel clears, generate a random value 0-255
+3. If the value is less than or equal to P (Persistence), wait TXDELAY then transmit
+4. Otherwise, wait SlotTime and repeat from step 1
+
+In full-duplex mode, CSMA is bypassed and packets transmit after TXDELAY.
+
+## SetHardware Extensions (0x06)
+
+MeshCore-specific functionality uses the standard KISS SetHardware command. The first byte of SetHardware data is a sub-command. Standard KISS clients ignore these frames.
+
+### Frame Format
+
+```
+┌──────┬──────┬─────────────┬──────────────┬──────┐
+│ FEND │ 0x06 │ Sub-command  │ Data (escaped)│ FEND │
+│ 0xC0 │      │   1 byte    │   variable   │ 0xC0 │
+└──────┴──────┴─────────────┴──────────────┴──────┘
+```

+| Reboot | `0x18` | - |
+| SetSignalReport | `0x19` | Enable (1): 0x00=disable, nonzero=enable |
+| GetSignalReport | `0x1A` | - |
+
+### Response Sub-commands (TNC to Host)
+
+Response codes use the high-bit convention: `response = command | 0x80`. Generic and unsolicited responses use the `0xF0`+ range.
+
+| Sub-command | Value | Data |
+|-------------|-------|------|
+| Identity | `0x81` | PubKey (32) |
+| Random | `0x82` | Random bytes (1-64) |

+| SignalReport | `0x9A` | Status (1): 0x00=disabled, 0x01=enabled |
+| OK | `0xF0` | - |
+| Error | `0xF1` | Error code (1) |
+| TxDone | `0xF8` | Result (1): 0x00=failed, 0x01=success |
+| RxMeta | `0xF9` | SNR (1) + RSSI (1) |
+
+### Error Codes
+
+| Code | Value | Description |
+|------|-------|-------------|
+| InvalidLength | `0x01` | Request data too short |
+| InvalidParam | `0x02` | Invalid parameter value |

+| MacFailed | `0x04` | MAC verification failed |
+| UnknownCmd | `0x05` | Unknown sub-command |
+| EncryptFailed | `0x06` | Encryption failed |
+
+### Unsolicited Events
+
+The TNC sends these SetHardware frames without a preceding request:
+
+**TxDone (0xF8)**: Sent after a packet has been transmitted. Contains a single byte: 0x01 for success, 0x00 for failure.
+
+**RxMeta (0xF9)**: Sent immediately after each standard data frame (type 0x00) with metadata for the received packet. Contains SNR (1 byte, signed, value x4 for 0.25 dB precision) followed by RSSI (1 byte, signed, dBm). Enabled by default; can be toggled with SetSignalReport. Standard KISS clients ignore this frame.

+## Notes
+
+- Data payload limit (255 bytes) matches MeshCore MAX_TRANS_UNIT; no change needed for KISS “1024+ recommended” (that applies to general TNCs, not MeshCore)
+- Modem generates identity on first boot (stored in flash)
+- All multi-byte values are little-endian unless stated otherwise
+- SNR values in RxMeta are multiplied by 4 for 0.25 dB precision
+- TxDone is sent as a SetHardware event after each transmission
+- Standard KISS clients receive only type 0x00 data frames and can safely ignore all SetHardware (0x06) frames
+- See [packet_structure.md](./packet_structure.md) for packet format
