The predefined size of input buffer is 88 bytes (defined by the SIMPLE_SERIAL_SHELL_BUFSIZE identifier). It's ok in most cases, but when it's not enough, you can redefine it with build options.
Check your IDE documentation to learn how to properly redefine build options. See the example for PlatformIO below.
Configuring buffer size from within the Arduino IDE is not recommended.
Define a new value at your platformio.ini in this way:
build_flags = -D SIMPLE_SERIAL_SHELL_BUFSIZE=128An example for Leonardo board looks this way:
leonardo.build.extra_flags={build.usb_flags} '-DSIMPLE_SERIAL_SHELL_BUFSIZE=128'
