+By default st initializes the serial line to 8 bits, no parity, 1 stop bit
+and a 38400 baud rate. The speed is set by appending it as last argument
+(e.g. 'st -l 115200'). Arguments before the last one are

+flags. If you want to set odd parity on 115200 baud use for example 'st -l
+parenb parodd 115200'. Set the number of bits by using for example 'st -l cs7
+115200'. See
