    XDemo18: Reads I-7000 series module's ID.

    Compiler: BC++ 3.1
    Compile mode: large
    Project: user.c
             v7000.c
             vModbus.c          [after vcom3002.lib]

             ..\Lib\VcomNNNN.Lib, with NNNN being the lib file's version.

    19  -> Any command will be accepted.

    This demo shows how to communication with 7000 series which connected
    to COM2 of 7188E.

    Hardware: 7188E + any 7000 series module whose address is 01,
                                                   baudrate is 9600,
                                                   checksum is disable.

    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.
