Your question is too general. Could you be more specific on the problem you faced. Are you looking for third party component?
Are you using delphi 1, 2 or 3?

The following is a simple example from Lloyd's help file:

program PortAccess;

var
  port: TextFile;
  x: char;

begin
  Assign(port, 'COM2');
  Rewrite(port);
  write(port, 'AS5', #13);
  { sample uses:
  read(port, x);
  write(port, x);
  }
  close(port);
end.
