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. |
