/**
* @file
* MINIMALISTIC SERIAL PORT DRIVER for COM1
* ========================================
* Call serial_init() **once** before _reading_ or _writing_ with
* serial_read() or serial_write().
*
* Blocking
* --------
* Please note that the calls will block if the buffers
* are full (and not read on the other end) _or_ no data is available
* for reading.
*
* Dependencies
* ------------
* The implmentation relies on x86_inb() and x86_outb()
* to be defined in _asm/x86.h_.
*
* Reference
* ---------
* The implementation was ruthlessly copied from here: https://wiki.osdev.org/Serial_Ports
