…mingHub#2560) This PR fixes a bug in the Esp8266 and Host uart driver implementations of `smg_uart_uninit` which causes subsequent calls to `smg_uart_init_ex` to fail as it thinks the port is in use. This bug is exposed if a port is opened, closed and then re-opened: ``` Serial.begin(COM_SPEED_SERIAL); ... Serial.end(); // optional - begin() calls this internally anyway Serial.begin(9600); // fails ``` Also add a `bool` return value from `HardwareSerial::begin()` method so caller can check for errors.
