title: U-Boot - Embedded Linux - Terminal Connection
body: <p>I have an embedded linux board with a max3222e RS232 converter. The pins are availlable on soldering pins. I think I've figured out the ground pin, the TX pin and the RX pin. When I connect my pc with a terminal program, I can see the boot logs of the embedde linux system. Also I can stop u-boot with pressing any key. But when I try to use some boot arguments then the characters of the pressed key are not the same like on the pc. For example:</p>
  
  <p>Enter->y</p>
  
  <p>a -> 0</p>
  
  <p>s -> F</p>
  
  <p>Can anybody tell me what's wrong. The serial settings are 115200 Baut 8N1 and no Flowcontrol.</p>
  
  <p>Thanks a lot</p>
