Serial Port ActiveX Control is a powerful and versatile ActiveX component that lets you control serial ports, manage them and track their activity. It is a great alternative to complicated WinAPI for serial ports.

In Serial Port ActiveX you will find diverse methods to read/write to and from serial ports, plenty of properties for advanced configuration of serial ports as well as the complete range of events to control them. Integrating Serial Port ActiveX in your own software is quite easy thanks to sample code for major development environments that is bundled with our component.

With Serial Port ActiveX you can

Communicate with external devices

Serial Port ActiveX Control is designed to communicate with external devices, connected via RS232/422/485, such as modems, bar code readers, PBX, medical instruments, IrDA, Bluetooth and USB serial devices and so on.

Fully control serial port activity

Our Serial Port component features a variety of events, methods and properties to let you fully track serial port activity. You will see when a port was opened or closed, which data was sent or received and so on immediately. You can change serial port timeouts, lice and handflow control, line signals and special characters directly from your application.

Manage serial port signal lines

All hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.) are fully supported.
