peek seems not working

[pinebud77]

It looks like the following code is working for me.

int AltSoftSerial::peek(void) { uint8_t head, tail;

head = rx_buffer_head;
tail = rx_buffer_tail;
if (head == tail) return -1;
if (tail + 1 < RX_BUFFER_SIZE)
    return rx_buffer[tail+1];
else
    return rx_buffer[0];

}
