Your string in "line" has a carriage return character at the end, 
which moves the cursor to the beginning of the display row.

If you remove this trailing carriage return character (0x0D) it 
will display correctly.

With the carriage return character in place, everything written 
to your terminal after the carriage return starts at the 
beginning of the row.
