Constant section:
 - HGTSER_MAX_PORT holds the number of managed port. Today 4.
 - HGTSER_WORD_5, HGTSER_WORD_6, HGTSER_WORD_7 and HGTSER_WORD_8 allow to 
   configure the number of bits per word.
 - HGTSER_STOP_BIT_1 and HGTSER_STOP_BIT_2 allow to configure the number of stop
   bit.
 - HGTSER_NO_PARITY, HGTSER_ODD_PARITY and HGTSER_EVEN_PARITY allow to configure
   the communication parity.
 - HGTSER_TX_QUEUE and HGTSER_RX_QUEUE are queues indentifiers.
 - HGTSER_RX_OVER is set when the reception queue is full and characters has 
   been lost.                                                                   
 
 - HGTSER_RTS_LINE is identifier of RTS line for Line status functions.
 - HGTSER_DTR_LINE is identifier of DTR line for Line status functions.

Type section:
 - TGTSER_PORT gathers data used to manage a serial port:
    * Port     indicates the selected port.
               G_COM1, G_COM2, G_COM3 or G_COM4
    * BaudRate is used to set port baud rate when open routine is called.
               300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
    * ITNumber indicates the interrupt number to use. The 0XFF value indicates
               the default value. Allowed number are from 0 to 15.
    * Mode     Memorises
               WORD size       : 5, 6, 7 or 8
               stop bit number : 1 or 2
               parity          : no parity, odd or even parity
    * TimeOut  indicates the time out value, in milli-seconds, at character
               level.
    * TxSize   is the transmit buffer size, in bytes.
    * RxSize   is the reception buffer size, in mbytes.
