ActiveXperts Serial Port Component is a software development kit (SDK) that enables the user to communicate to a device over a serial interface.

(long time ago delphi user) The lazarus serial package (LSP) seem to insert a return as the Arduino does not send it. Possible causes: communication is slow and if the LSP doesnt receive any char it might do an. To open a serial port, first access a SerialPort object. For this, you can either prompt the user to select a single serial port by calling navigator.serial.requestPort, or pick one from navigator.serial.getPorts which returns a list of serial ports the website has been granted access to previously. // Prompt user to select any serial port.

Such a device can be: a weight indicator, a modem, a scanner, or any other device that is equiped with a serial port. It can even be another PC, connected via a NULL modem cable.

ActiveXperts Serial Port Component features the following:

  • Direct COM port support (like 'COM1')
  • TAPI (Windows Telephony Device) support (like 'Standard 56000 bps Modem');
  • Support for RS-232/RS422/RS485, up to 256 simultaneous ports;
  • Support for all types of Hayes compatible modems;
  • Support for serial cable as well as USB cable or Bluetooth connections;
  • Support for Virtual COM ports (i.e. COM ports redirected through the network);
  • Hardware flow control (RTS/CTS, DTR/DSR) and software flowcontrol (XON/XOFF) support;
  • Configurable baudrate/parity/stopbits, full buffered data transfer, text/binary data transfer.

Step 1: Download and install the ActiveXperts Serial Port Component

Download the ActiveXperts Serial Port Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new Delphi Project

Launch Delphi from the Start menu. Choose 'New' from the 'File' menu and select your preferred kind of application, for instance: 'VCL Forms Application - Delphi for Win32'. A new Form is displayed in the workspace.

Step 3: Refer to the ActiveXperts Serial Port Component Library and create the objects

Now that a new project has been created, you must add a reference to Serial Port Component in the project to be able to use the ActiveXperts Serial Port Component object. To do so, choose 'Import Component...' from the 'Component' menu. The Import Components' dialog appears. Select 'Import a Type Library':

In the 'Components' page, leave all fields default and click 'Next':

(Click on the picture to enlarge)

In the 'Install' page, select 'Create Unit' and click 'Next':

The interface code is generated now and is shown in the AXSERIAL_TLB tab of the project.

Step 4: Declare and create the object

From the Project Manager, open Unit1.bas and add the AXSERIAL_TLB to the 'Uses' statement to refer to the ActiveXperts Serial Port Component library:

In the 'private' or 'public' section, declare the following objects:

You can now create the objects, for instance in the 'FormCreate' function:

Step 5: Send an AT command to a connected Hayes compatible modem

You can now send and/or receive data to and/or from a serial port.

The following code shows how to query a modem:

There are many working samples included with the product. You can also find them on the ActiveXperts FTP site: ftp.activexperts-lab.com/samples/serial-port-component.
