/**
* @file config.h
* @brief AT command configuration module for TCP2UART
*
* Handles UART1 AT commands for network and serial port configuration.
*
* Supported AT commands:
* - AT+IP=192.168.1.100 Set device IP
* - AT+MASK=255.255.255.0 Set subnet mask
* - AT+GW=192.168.1.1 Set gateway
* - AT+PORT=8080 Set TCP Server listen port
* - AT+RIP=192.168.1.200 Set TCP Client remote IP
* - AT+RPORT=9000 Set TCP Client remote port
* - AT+BAUD1=115200 Set UART2 baudrate
* - AT+BAUD2=115200 Set UART3 baudrate
* - AT+MAC=00:11:22:33:44:55 Set MAC address
* - AT+DHCP=0/1 Enable/disable DHCP
* - AT+SAVE Save parameters to Flash
* - AT+RESET Reset device
* - AT+DEFAULT Restore factory defaults
* - AT+? Query current configuration
* @brief Final AT configuration model for TCP2UART.
