Use ZylSerialPort component to easily communicate with external devices on serial port connection, such as modems, bar code readers, GSM modules and others. It works in synchronous and asynchronous mode. You can use it also with USB, IrDA and Bluetooth devices, because these devices have a driver that redirects the input from the USB, IrDA or Bluetooth port to a virtual serial port (you can check it in System/Device Manager/Ports).

If your USB device is not provided with such a driver, then use a USB controller whose vendor provides a virtual serial port driver, such as or use a USB/RS-232 adapter. The demo version is fully functional in Delphi and CBuilder IDE, but it displays a nag dialog (the licensed version will, of course, not have a nag dialog and will not be limited to the IDE). The package includes demo programs for Delphi and CBuilder and a help file with the description of the component.
