Learn How To Easily Work With A COMPort On Linux In Delphi Using A WINSOFT Library


Using this awesome library you can track and use all available ComPorts on your linux machine.

To make it work just download and add the library path, declare the units and call its functions, it is easy, fast and efficient.

Follow the tutorial to learn how to implement this. In my case i was working with a Windows host running Ubuntu on VirtualBox.

Installing Development Packages

To install the development packages on Ubuntu:

  1. Right-click your desktop and select Open Terminal.
  2. To upgrade the packages you have already installed , type sudo apt update && sudo apt upgrade && sudo apt dist-upgrade in the terminal.
  3. Type your user password and press Enter
  4. Wait until prompted to agree to the package upgrade operation. Type Y and press Enter
  5. Wait until the package upgrade operation is complete. It may take a few minutes to complete.
  6. To add the development packages, type sudo apt install joe wget p7zip-full curl openssh-server build-essential zlib1g-dev libcurl4-gnutls-dev libncurses5 in the terminal.
  7. Type your user password and press Enter
  8. Wait until prompted to agree to the package installation operation. Type Y and press Enter
  9. Wait until the pacjage installation operation is complete. It may take a few minutes to complete.

Preparing Your Linux Machine

To create Linux applications, you need to add a virtual machine PAServer:

1. Find the LinuxPAServer21.0.tar.gz file in the following location on your windows machine, and send it to your linux machine:

C:Program Files (x86)EmbarcaderoStudio21.0PAServerLinuxPAServer21.0.tar.gz
2. Unpack the LinuxPAServer21.0.tar.gz file.
  1. Right-click the folder where you have unpacked the LinuxPAServer21.0.tar.gz file, and then click Open in Terminal.
  2. Enter ./paserver in terminal. Then, press Enter.
  3. Set your password.

Now that the machine is ready to receive the deploy from windows, lets check how to implement the code, by the way, there are a simple demo showing how to work whit the library, you can download it here.

After download and open the demo project, follow the steps below to setup and deploy.

Remember to download the SDK for the target Linux OS.

Creating a Connection Profile

  1. On the Tools > Options > Environment Options > Connection Profile Manager page, click the Add button. The Create a Connection Profile wizard opens.
  2. On the Profile information page, enter the following:
    • In the¬†Profile name¬†field, enter the needed name.
    • In the¬†Platform¬†field, click the¬†64-bit Linux¬†platform.
    • Click¬†Next.
  3. On the Remote machine information page, enter the following:
    • In the¬†Remote machine¬†field, enter the IP address or Machine name.
    • Click¬†Test Connection¬†to check if the values are valid.
  4. Click Finish.

Adding the Installed SDK to RAD Studio

    • In the¬†Select an SDK version¬†field, the name of the SDK that you just installed will automatically appear. If you have not installed SDK previously, you can do it on this step. If you have already installed SDK, move on to the next step

As you can see on the demo project, just declare the unit LComPort, to track and use the Ports declare the following variables:

Then you can use the following code to list them all:

and to send some data through the Port:

Hope you guys succeeded to make it work, looking forward to see what comes next.
