Grove - Wio-E5 stopped responding to AT commands after sending AT+UART=TIMEOUT,0

Hello Guys,

Need some help,
I was successfully communicating with the Grove - Wio-E5 module by u usb/serial convertor and using MicroRidge ComtestSerial as terminal software.

The Grove - Wio-E5 answered as expected until I did send the AT+UART=TIMEOUT,0 command.
How can I set the timeout back to 300?

Thanks in advance,
Michel
