The function terminates if the terminator character is detected, the determined length has been read, or it times out (see <a class='wikilink' href='Serial_SetTimeout.html'>Serial.setTimeout</a>()). </p> <p class='vspace'></p><p>Serial.readBytesUntil() returns the number of characters read into the buffer.
