opening a serial port in a specific way

hi here!
sorry for askin that but maybe someone has time for a rookie .
need to open a com port in that way:

I/O Request (DOWN) 
IOCTL_SERIAL_SET_BAUD_RATE: Set baud rate 
Baud Rate=38400 

I/O Request (UP) 
IOCTL_SERIAL_SET_BAUD_RATE: Set baud rate 

I/O Request (DOWN) 
IOCTL_SERIAL_CLR_RTS: Clear RTS 

I/O Request (UP) 
IOCTL_SERIAL_CLR_RTS: Clear RTS 

I/O Request (DOWN) 
IOCTL_SERIAL_SET_DTR: Set DTR 

I/O Request (UP) 
IOCTL_SERIAL_SET_DTR: Set DTR 

I/O Request (DOWN) 
IOCTL_SERIAL_SET_LINE_CONTROL: Set line control 
WordLength=8 
StopBits=1 stop bit 
Parity=No parity 
I/O Request (UP) 
IOCTL_SERIAL_SET_LINE_CONTROL: Set line control 

I/O Request (DOWN) 
IOCTL_SERIAL_SET_CHARS: Set special characters 
EofChar=0x0 
ErrorChar=0x0 
BreakChar=0x0 
EventChar=0x0 
XonChar=0x7f 
XoffChar=0x7e 
I/O Request (UP) 
IOCTL_SERIAL_SET_CHARS: Set special characters 

I/O Request (DOWN) 
IOCTL_SERIAL_SET_HANDFLOW: Set handshake information 
ControlHandShake=1 
FlowReplace=0 
XonLimit=2048 
XoffLimit=512 

I/O Request (UP) 
IOCTL_SERIAL_SET_HANDFLOW: Set handshake information 

I/O Request (DOWN)IOCTL_SERIAL_SET_TIMEOUTS: Set timeouts 
ReadIntervalTimeout=1 
ReadTotalTimeoutMultiplier=0 
ReadTotalTimeoutConstant=0 
WriteTotalTimeoutMultiplier=30 
WriteTotalTimeoutConstant=100 

I/O Request (UP) 
IOCTL_SERIAL_SET_TIMEOUTS: Set timeouts 

I/O Request (DOWN) 
IOCTL_SERIAL_PURGE: Purge requests 
Purge mask=TXCLEAR: Write requests, RXCLEAR: Write buffer 

I/O Request (UP) 
IOCTL_SERIAL_PURGE: Purge requests 

I/O Request (DOWN) 
IOCTL_SERIAL_SET_WAIT_MASK: Set current event mask 
WaitMask=RXCHAR: Any Character received 

I/O Request (UP) 
IOCTL_SERIAL_SET_WAIT_MASK: Set current event mask 

Write Request (DOWN) 
Buffer size: 0x1 bytes 
F0  

Write Request (DOWN) 
Buffer size: 0x2 bytes 
28 01  

I/O Request (DOWN) 
IOCTL_SERIAL_PURGE: Purge requests 
Purge mask=TXCLEAR: Write requests, RXCLEAR: Write buffer 

I/O Request (UP) 
IOCTL_SERIAL_PURGE: Purge requests

(down) means data sent to com port
(up) means confirmation from com port, i added just in case .

need a small app(vb/32bit) to run settings above.
the app it should start with a small gui window where com port number can be set manually and an "ok " button to confirm .


closing the app, com port must return to windows default settings .
thank you
