[Ver8.1]:
  1. Baudrate up to 921600 bps
---------------------------------------------------------------------------------------------------------------

[Ver6.2]:
  1. Baudrate setting 
   	switch(baudrate)
	{
		case 1200 :   dcb.BaudRate=CBR_1200;    break;
		case 2400 :   dcb.BaudRate=CBR_2400;    break;
		case 4800 :   dcb.BaudRate=CBR_4800;    break;

		case 115200 : dcb.BaudRate=CBR_115200;  break;
		// ERROR CODE=3, baudrate error 
		default: return BaudRateError; 
	}
    Change to ........
    	dcb.BaudRate = baudrate;

[Ver6.1]:
  1. CMD_LEN is defined for Send/Receive buffer size,
     now change the buffer suze to 1024 from 80.

[Ver6.0]:   Open Multiple COM Port at the same time
  1. add the following function
     EXPORTS WORD CALLBACK ComPortStatus(char port);
     //  1: this port is used now
     //  0: this port isn't used now
  2. removing the following functions
     EXPORTS WORD  CALLBACK Send_Cmd(char cPort, char szCmd[], WORD wTimeout, WORD
              wChkSum);
     EXPORTS WORD  CALLBACK Read_Com_Status(char cPort, char szResult[], WORD
              *wT);
     EXPORTS WORD  CALLBACK Send_Str(char cPort, char szCmd[], WORD wTimeOut, WORD
              wLenT, WORD wLenR);
---------------------------------------------------------------------------------------------------------------

[Ver5.1] :  Because [Ver5] not finished. So Please using [Ver5.1] to develop uart.dll
---------------------------------------------------------------------------------------------------------------
[Ver5] :  [Ver4] with support 255 COM Port.
---------------------------------------------------------------------------------------------------------------
[Ver4] :  Read/Write with Non-Overlapped, 
          rewrite the following function:
              Send_Cmd(),
              Read_Com_Status(),
	      Send_Str().
---------------------------------------------------------------------------------------------------------------

[Ver3] :  Read/Write with Non-Overlaped 
---------------------------------------------------------------------------------------------------------------

[Ver2] :  Read/Write with Original
