This command configures the USART communication parameters. It takes parameters for mode (0 for asynchronous), data bits (8), parity (0 for none), stop bits (0 for 1 stop bit), flow control (0 for none), and baud rate (115200). The two '0's before the baud rate are likely for modem line control or reserved fields.

```Protocol Commands
-> SET COM 0,8,0,0,0,0,0,115200
```

### Configuring RTX Thread Stack Size in C

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/DoxyGen/src/DV_WiFi.txt

This C preprocessor directive sets the default stack size for RTOS threads to 400 bytes. This configuration is typically found in `RTX_Config.h` and is crucial for allocating sufficient memory for thread execution, preventing stack overflows.

```C
#define OS_STACK_SIZE           400
```

### Receiving Data - USART Command Protocol

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/STM32F429I-DISC1/Abstract.txt

This command initiates a data reception operation. The parameters specify the transfer direction (0 for receive), the number of bytes (16), an offset (0), and a timeout (100 ms). It returns the received bytes.

```USART Command Protocol
-> XFER 0,16,0,100 <-
```

### Controlling Modem Line State - USART Server - Protocol Commands

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/MCBSTM32F400/Abstract.txt

This command controls the state of a modem line. It takes a modem line mask (01 for RTS), a delay before activation (10 ms), and a duration for activation (50 ms) as parameters. The line will be activated for the specified duration after the delay, then deactivated.

```Protocol Commands
-> SET MDM 01,10,50
```

--------------------------------

### Sending Data - USART Command Protocol

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/STM32F429I-DISC1/Abstract.txt

This command initiates a data transmission operation. The parameters specify the transfer direction (1 for send), the number of bytes (16), an offset (0), and a timeout (100 ms). It expects 16 bytes to be sent.

```USART Command Protocol
-> XFER 1,16,0,100 ->
```

--------------------------------

### Setting SPI Server Receive Buffer (SPI Server Command)

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/SPI_Server/Board/STM32F429I-DISC1/Abstract.txt

Sets a specific byte in the receive (Rx) buffer. The command takes the buffer type (RX), an offset, and the hexadecimal value of the byte to set (e.g., 3F for '?').

```SPI Server Command
SET BUF RX,0,3F
```

--------------------------------

### Bidirectional Data Transfer - USART Server - Protocol Commands

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/MCBSTM32F400/Abstract.txt

This command initiates a bidirectional data transfer, applicable only in synchronous mode. It specifies the transfer direction (2 for bidirectional), the number of bytes to transfer (16), an offset (0), and a timeout (100 milliseconds). Both client and server exchange the specified number of bytes.

```Protocol Commands
-> XFER 2,16,0,100 <->
```

--------------------------------

### Setting Modem Line State - USART Command Protocol

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/STM32F429I-DISC1/Abstract.txt

This command controls the state of a modem line, specifically activating RTS. The parameters specify the modem line mask (01 for RTS), activation delay (10 ms), and active duration (50 ms).

```USART Command Protocol
-> SET MDM 01,10,50
```

--------------------------------

### Setting Communication Parameters - USART Command Protocol

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/STM32F429I-DISC1/Abstract.txt

This command configures the USART communication parameters. The parameters specify asynchronous mode (0), 8 data bits (8), no parity (0), 1 stop bit (0), no flow control (0), and a baud rate of 115200.

```USART Command Protocol
-> SET COM 0,8,0,0,0,0,0,115200
```

--------------------------------

### Disabling Telnet Server Authentication (C)

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/DoxyGen/src/DV_WiFi.txt

This C code snippet disables authentication for the Telnet server by setting TELNET_SERVER_AUTH_ENABLE to 0. This configuration in Net_Config_Telnet_Server.h allows direct access to the Telnet service without requiring credentials, useful for debugging.

```C
#define TELNET_SERVER_AUTH_ENABLE   0
```

--------------------------------

### Setting SPI Server Transmit Buffer (SPI Server Command)

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/SPI_Server/Board/STM32F429I-DISC1/Abstract.txt

Sets a specific byte in the transmit (Tx) buffer. The command takes the buffer type (TX), an offset, and the hexadecimal value of the byte to set (e.g., 53 for 'S').

```SPI Server Command
SET BUF TX,0,53
```

### Transferring Data Bidirectionally - USART Command Protocol

Source: https://github.com/arm-software/cmsis-driver_validation/blob/main/Tools/USART_Server/Board/STM32F429I-DISC1/Abstract.txt

This command initiates a bidirectional data transfer, typically used in synchronous mode. The parameters specify the transfer direction (2 for bidirectional), the number of bytes (16), an offset (0), and a timeout (100 ms). It involves both sending and receiving 16 bytes.
