AjK 0:eb2522b41db8 49 * <b>MODSERIAL</b> extends the Mbed library <a href="/handbook/Serial">Serial</a> to provide fully buffered
AjK 0:eb2522b41db8 50 * TX and RX streams. Buffer length is fully customisable.
AjK 0:eb2522b41db8 51 *
AjK 0:eb2522b41db8 52 * Before using MODSERIAL users should be familar with Mbed's standard <a href="/handbook/Serial">Serial</a>
AjK 0:eb2522b41db8 53 * library object. MODSERIAL is a direct "drop in" replacement for <a href="/handbook/Serial">Serial</a>. Where
AjK 0:eb2522b41db8 54 * previously Serial was used, MODSERIAL can be used as adirect replacement instantly offering standard
AjK 0:eb2522b41db8 55 * TX and RX buffering. By default, both TX and RX buffers are 256 bytes in length.
