In some cases, the break sequence can be transmitted improperly when a USB/Serial converter cable is used. In such cases, use a keyboard with a different connector port (for example, a PS/2). How to Simulate a Break Key Sequence
For hardware serial high baud rates can be used. For Arduino Mega 500000 baud works good. The ChangeBaudRate sketch can be used to change the default baud rate of the AT firmware to a higher one for hardware Serial. For example a WebServer serving web files from SD card requires high ba...
