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

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

Solution 1

need a small app(vb/32bit) to run settings above.
You could use one of the free terminal programs that Google will find for you (Hyperterm, putty etc), or you could write it yourself.

sorry, no skills workin with scripts , only thing i did by myself was recording data traffic.
also most of utilities from net who override windows serial port settings are blocking data coming out from com device.
just hoping to find some help here......

I'm not sure I understand what you are saying here. What do you mean "scripts", this is surely a programming problem. Also what do you mean by "most of utilities from net who override windows serial port settings are blocking data coming out from com device."? If that was the case then none of them would work. Maybe you need to reword your question.

used that to set com port settings and send hex data to device as in captured data i posted ,get same data from the device as original utility that im trying to skip but data stucks somewhere didnt reach the target app.
so if you agree this aint an easy job why are you send me for googleling ?

Sorry where did I say that?
I would suggest you edit your original question and explain more clearly what you are trying to do and why it is not working. The comments above are not very clear.

what so hard to understand ? , my first post shows very clear what happens to com port .

once copleted all sequences(on yellow field above) data can run from a rs232 external device to a target app .

i was only asking for a small utility, exe , driver, say it as you wish ,to to make any(any=thats what i asked for setting com port number before run)com port behave like this.

thats does original utility , and im trying to replece it cuz its a part from a huge app with a lot of limitations.

thank you

As I said before, you will need to either find something via a Google search, in the articles here on CodeProject, or write it yourself. I cannot conjure such an application out of thin air for you.

Richard MacCutchan 16-Jan-12 7:15am

I have just taken a quick look at your link and it appears you are trying to implement the code posted on that site; I would suggest you post your questions there so the author of the code can answer you.

nothing to to with that utility from noah , only similarities.

i recorded traffic from another utility (much more parameters to set).
