outp();

I have an application written for win16. In this program I use outp in order to give add on card information. However this does not work with win32. Could someone describe me how this should be done.

Just a suggestion...

Can you make your old Win16 code into 16-bit DLL and then mix your Win32 app with 16-bit DLL?..

It's only assumption...

A 32 bit app can't call a 16 bit DLL directly. You would have to use thunks to make the call work. (then it would work.)

Andrei Rodionov

OK. I just mean it.

ekinee,

I use a shareware-driver, called "TVicHW32" for this.

If you stick to win95/win98 you can still use outp() etc...

1. Codes directly from my application so please do not confuse by the parameter names.

2. Create a handle to the port as given below.

hCommPort = CreateFile (m_PortName, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

m_PortName can be COM1/COM2/COM3/COM4

3. Write to the port using the hCommPort handle and the WriteFile function. Configure the m_strWrite String with the details of the add-on Card.

WriteFile(hCommPort, m_strWrite, dwLength, &MyBytesWritten, NULL);

I have assumed that you have the source code to rebuild.

nietod

padmashali, that allows you to access a communication port, not an I/O port. The two are unrelated. outp() allows you to access the 64k I/O ports on an x85 machine.

Yes, as nietod said I dont want to communicate with the card through COM port, but through ISA bus.

I've found the device driver that does what I want .

So I'm thanking.

Thanks nietod, and sorry for not understanding the Q and answering.
