An RS-232 serial console servers to be controlled from a terminal or a PC with a terminal emulation program attached to the asynchronous COM1 (or other) serial port. If your Windows PC doesn’t offer a terminal emulation program (e.g. Your PC is running Windows 7), please use Tera Term.
Suggestion: use rn instead of only n and check the results.
Suspecting that Teraterm is not configured correctly but here are on topic threads:
Thank you for your help, but I make the configurations on tera term according with this https://developer.mbed.org/handbook/Terminals and I think this is not incorrect. I checked this configuration repeatedly...

Jane - did you apply the following in the setup of Teraterm ?
Setup New-line format (to print out new line characters correctly)•Setup -> Terminal... •Under 'New-line', set Receive to 'LF'

Yes, I did this configuration too. But anyway, if I don't press the 'send break' or the 'Del', nothing happens.

See here:
Pause time while the break signal is sending to the serial port
When the break signal is sent to the serial port, the default pause time is 1000 msec. To change the pause time, edit change the SendBreakTime entry in the [Tera Term] of the setup file. SendBreakTime=2000
Default:SendBreakTime=1000

perhaps related to a buffering / timeout issue of the FIFOs (buffers) so the above is worth testing. Try smaller delays.
