    XDemo24: Uses countdown timer

    Compiler: BC++ 3.1
    Compile mode: large
    Project: user.c
             v7000.c
             vModbus.c          [after vcom3002.lib]
             ..\Lib\7188EL.Lib
             ..\Lib\TCPIP32.Lib
             ..\Lib\VcomNNNN.Lib, with NNNN being the lib file's version.

    When 7188E power on, the demo will start running countdown function.

    There are 8 countdown timer (channel 0 to channel 7)
    This demo uses channel 0.
    The countdown timer initial value is 1000 ms.
    When the countdown timer value become 0,
    the value of LED will increase.

    Hardware: 7188E with 5-digit LED display.

    Refer 7188e\TCP\Doc\[Big5|Eng|Gb2312]\Vxcomm.htm 
          7188e\TCP\Xserver\Xserver.htm
          7188e\TCP\Xserver\Function.htm   
    to get more information.
	
	Because the kernal of Xserver used InstallCom() function.
	Please use printCom1() instead of Print() if you want to send formatted output from COM1.
