The telnet example prints a line to the console, but it is not ended with a newline. When using pyterm, the last line is then never shown as it reads the console line by line and is waiting for the end of the line. This patch swaps use of `printf` for `puts` for the last line printed. This means the missing newline character gets added. This is also done to be consistent with the rest of the file, where puts is used whenever possible instead of printf.
