title: UART to UART Bridge STM32
body: <p>is there a simple way to "bridge" 2 U(S)ART Lines (USART1 &amp; UART5 on STM32F107) by software? </p>
  
  <p>I need to forward the data which are incoming at USART1 to the UART5 and reverse.</p>
  
  <p>Current MCU is STM32F107VCT7</p>
  
  <p>Main reason why I want to do that is to update a Device over UART which is connected to my MCU. The MCU is connected to PC.</p>
  
  <p>PC --- STM32 --- Other Device</p>
