Hi,
map the USB Port to a Virtual Serial Port and open the Port as File using
CreateFile using name "\\.\COMxxx"
Then write to the port with the usual API file commands
Even better wrap this to a Stream (or FileStream) descendant and use
Stream.Write commands
Read and Seek should do nothing
I h
be tricky to cover all
cases.
Your proposal on the name/value pair reminds me of Qt but in the Delphi/Fpc
world it is done with rtti.

Hi,
FPC does not support copy-construction so either you must override the
TPersistent.Assign method or in case of TComponent you can use
ReadComponent/WriteComponent.
You should also take into account deep vs swallow copy semantics as well as
the type of the container and contained classes

Hi all,
I am not sure about the constructor case but I consider the FPC
implementation of generics much more powerful than Delphi's assuming that
Sven's comment actually works as expected.
The fact that the method invocation is actually checked on specialization
and not on declaration means that s
his is not possible I do not know if it
can be done.
If you do not care about that then just use java glue code, it's simpler.

Hello everyone,
a couple years ago i tried the same thing. The task was to implement a
JavaPOS driver handler from Delphi/FPC code.
The actual driver was implemented in C++ and it used a Java interface. My
code was the glue between the application (Delphi/FPC) and the driver, it
had to hook the ev
