	Programming the RS232 port is not easy. I am afraid; you have to spit through the code to see how the predicates are used. At essential points, I made a short comment, especially in the user interface part, to make your live a little easier. I think you should start there. Then there are two examples, where you can see how events are handled.		Programming the RS232 port is not easy. I am afraid; you have to spit through the code to see how the predicates are used.

The first program has been developed under Windows XP sp2 but XP is no longer supported. However, the kernel32.lib I use is still the same and works under Windows 7,8 and 8.1.

	Using the packages, I wrote this test program for inspecting the RS232-communication at a very basic level. It reads out the buffer of a port at your command and you can send a byte sequence over the line. You should read the help file to discover how to do these things.

In this program you find packages for communicating via the RS232-interface of a computer. There is a native_class for the external predicates and an api_class for the glue_code. These two classes are the heart of the program.

Every port is seen as an object. So there is a serialport_class for interfacing. In that way it should be possible to use more ports at the same time.

To make RS232-communication possible between Visual Prolog and a microcontroller was the reason for building the program. The hardware demands are very small: pin two, three and ground is all that is needed. This means also that not all external predicates are present.

I had to use Kernel32.Lib which can be found in the PlatformSDK from Microsoft.
Distributing this library is not possible here . You have to get to the Microsoft-site for downloading the SDK, in case you do not have it already.

Furthermore, you have to use the commercial edition of VIP because the program uses multi-threading. That was unavoidable.

The program has been developed under WindowsXP sp2 and I used the latest edition of VIP: version 7103. The library I use was downloaded two years ago. Very recently I tested the compiled program on a laptop under Vista with an USB_to serial_converter. I had no problems there so far.

Using the packages, I wrote this test program for inspecting the RS232-communication at a very basic level. It reads out the buffer of a port at your command and you can send a byte sequence over the line. You should read the help file to discover how to do these things.

There is no protocol. Just a byte sequence. If you should decide to use the packages then you might have to develop a protocol yourself.

At essential points, I made a short comment, especially in the user interface part, to make your live a little easier. I think you should start there.
