com port communication with a device

How can I write a program which are communication with a device which is
connected to comport? The device reuirements are below:
  - The data format of the interface is 4800 baud,
  - 1 start bit,
  - 8 data bits,
  - 1 stop bit,
  - no parity.
  -  For the protocol,XON/XOFF should be set. Data are transmitted and
received
as ASCII characters.

For this communication I can use some codes and some components. But I was
not able to do this.
hComm = CreateFile("COM1",
                      GENERIC_READ | GENERIC_WRITE,
                      0,
                      NULL,
                      OPEN_EXISTING,
                      0,
                      NULL);

I am thinking that my problem is about handshaking(1 start bit, ASCII,
XON/XOFF) ... etc.

But I did not solve this. Can you help me about this problem.

Best regards.
