I have seen several complex embedded Delphi systems in several industries running smoothly. And they have used 3rd parts components or libraries for data communications. One of the best and known toolkits is the Async Professional which provides direct access to serial ports, TAPI, and the Microsoft Speech API. It supports faxing, terminal emulation, VOIP, and more.
What can you do with a serial port in an embedded system?
- External device communication
- Peripheral communication bridge
- Debugging interfaces
- and much interesting stuff
You can utilize Async Professional with C++ Builder or Delphi. Moreover, AsyncPro also supports faxing, terminal emulation, VOIP, and more.
Head over and find out more information about the AsyncPro VCL and then download it via the IDE.
