 ### WiFiST
 * Class constructor changed, 3 new constructors depend on the communication driver:
 `WiFiClass(SPIClass \*SPIx, uint8_t cs, uint8_t spiIRQ, uint8_t reset, uint8_t wakeup);`
-`WiFiClass(HardwareSerial \*UARTx, uint8_t reset, uint8_t wakeup);`
+`WiFiClass(Uart \*UARTx, uint8_t reset, uint8_t wakeup);`
 `WiFiClass(uint8_t tx, uint8_t rx, uint8_t reset, uint8_t wakeup);`
 * `status()`: less verbose; only `WL_CONNECTED`, `WL_NO_SHIELD`, `WL_IDLE_STATUS`, `WL_NO_SSID_AVAIL`, `WL_SCAN_COMPLETED`, `WL_CONNECT_FAILED` implemented.
 * `setMac()`: function added to set MAC address of the Wifi module.
