codegear(c++) and serial port

Can anybody help me find free components or any other easy way to communicate with device attached to the seria开发者_StackOverflow中文版l port? I'm using Codegear and quite desperate after few days of googling.

boost.asio has support for serial ports:

Try using old Borland C++ resources, are compatible with embarcadero.

Codegear is also compatible with delphi libraries http://delphi.icm.edu.pl/
