• no need to distribute additional files, cause madExcept is fully linked into your executable
• the size of your executable file grows only by some percent (usually single digit)
• you don’t need to change a single line of code in your project
• there’s no performance loss, as long as no exception occurs
• full support for multi threaded applications
• full support for third party translation tools
• full support for third party protection/compression tools
• email, web upload and printing functionality included
• free for non-commercial usage, inexpensive for commercial usage

Do you need to write a multithreaded applications ? Are you annoyed of writing lines and lines of code for threads synchronization and CriticalSections for data protection ? Would you believe that the thread is just a click away ? Well here it is, the TBMThread is a native VCL component implementing everything you do need to create the thread and the synchronization, just dropping the component on the form. Sounds great, right ? And it’s not all. Here is the Thread group now. Just set couple of therads to point to one and the same group and you can control and monitor all of them. Well this is a beta version. Even more fun is ahead. So enjoy. Does have a component package.

ZylSerialPort is a Delphi & C++Builder thread based asynchronous serial port component. Use ZylSerialPort component to easily communicate with external devices on serial port connection, such as modems, bar code readers, GSM modules and others.

You can use it also with USB, infrared and Bluetooth devices, because these devices have a driver that redirects the input from the USB, infrared 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 FTDI or use a USB/RS-232 adapter.
