Thenard,
You need to create a program in a lower level language, eg C.
In our case we had to load data via the client's Com port into the
database, with transfer initiated from an Oracle Form.
A design decision was made to use a two-phase operation.
First a Windows .DLL runs on the Client, reading data from the Com port and
creating a text file.
The ORA_FFI (Foreign Function Interface) package provides the means to
access DLL functions from within a Form.
Subsequently the Form read the text file, using TEXT_IO procedures, and
updated the database.
I'm told that Oracle provides a demo form with Developer/2000 called
FFI_GEN.
Hope this gives you some idea of what's required.
