Raw Message I have a rather extensive comm unit created in Delphi for communication with a data acquisition instrument via RS232. The task is to port a project using this file to Lazarus on Linux. Thanks to advice here I have found a serial port component that works in similar ways to the one I have used in Windows, so now I am embarking on the porting task. In the existing unit the serial port communication component is instantiated in code rather than being dropped on a form.

Now I believe I have two options: 1) Sprinkle the code with conditionams for Delphi/Lazarus and use the 5dpo component and its specific calls for Lazarus and the existing code for Delphi. This will be rather ugly since the comm object FComm is used in many places in the code. Or 2) Maybe I can somehow disguise the actual implementation of FComm from my existing code and instead create a 5dpo object in Lazarus and the other type in Windows, but give the wrapper the same properties and methods as the existing component has. This would involve wrapping 5dpo in a superclass, which translates the used properties/methods into 5dpo specifics. Then I would be able to select the proper one to make based on conditionals inside a different unit from my main unit. But how would this be done more specifically? Is there some description available on making code compatible between Delphi and Lazarus when there are component differences in the two systems as I described above?

(I don't know if this is off-topic here and should be posted to the fpc list instead, but since GMANE does not yet allow posting to the fpc group I hope you will not be offended by me posting this question here. God Eater Burst Data Pack Usa more. It seems like it is both a Lazarus vs Delphi question and one regarding subclassing.) Bo Berglund.

The 5dpo Component Library. TSdpoSerial allows asynchronous communication using a serial port. Added icon to SdpoFastForm and Lazarus 0.9.28 support. I would advise you to go to the newer tutorial about talking to things over a serial cable from a Windows computer. Livro Fisica Conceitual Download Pdf. In our simple approach to serial communication over the comm port, we're going to have to do in software what can be done in hardware with more. Bible Lazarus Raised From The Dead. Delphi-Lazarus compatible code including serial port. Here I have found a serial port component that. Google just leads me to bible quotes (Lazarus).

Well, that is not really possible. In other parts of the software we build there is a lot of Delphi and Windows specific stuff, like components only available for Delphi, access to databases via ADO and what have you. The task before me is to use some preexisting classes from our Delphi system in a Lazarus project that can be ported over to Linux. We intend to include a Linux based touch panel front-end to the instrument and when programming that I have zoomed in on Lazarus in order to re-use existing Delphi code.

Hinton Drivers Test here. So I will use conditionals to make the class unit compatible to Lazarus and Delphi. What is its issue number in the bug tracker?

Sorry I don't know how to search the bug tracker. Some days ago someone in some Forum posted that 'Synchronize is not implemented as sophisticatedly as in Delphi and therefor if many Synchronizes are fired simultaneously the Application will hang'.
