<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">The stm32h7_uart_set_attributes function incorrectly set the UART mode to UART_MODE_RX when the POSIX CREAD (Enable Receiver) flag was cleared in the termios control flags.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">This inadvertently disabled the transmitter (breaking console output) and left the receiver enabled, which is the exact opposite of the intended behavior.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">This commit fixes the fallback logic to set the mode to UART_MODE_TX when CREAD is not set, ensuring that the console can still transmit data while reception is properly disabled.</p>
