Define Character Stuffing?
In byte stuffing (or character stuffing), a particular byte is added to the data section of the frame when there is a character with the same pattern as the flag. The data section is stuffed with an extra byte. This byte is usually known as the escape character (ESC), which has a predefined bit pattern. Whenever the receiver encounters the ESC character, it deletes it from the data section and treats the next character as data, not a delimiting flag.
