tu masz opis prosto z pliku README.txt
For Delphi 3, 4, 5, 6, 7, 2005 & C++ Builder 4, 5, 6:
(C++ Builder users also need to read the C++ Builder notes)
Use "File/Open" menu item in Delphi/C++ Builder IDE to open
ComPort run-time package source file (see above). Click "Compile"
button in Package window to compile the library. Now move run-time
package library file or files (see above) from ComPort folder to a
folder that is accessible through the search PATH (e.g. WinNT\System32).
Now you have to install design-time package. Use File/Open menu item
to open design-time package source file (see above). Click "Compile"
button in Package window to compile the package and "Install" button
to register ComPort into the IDE. ComPort components appear in
"CPortLib" page of component pallete. If it complains that it
can't install it because it can't find a library, you probably
did not put the run-time package in the search path. You might
not get this error until the next time you try to start
Delphi/C++ Builder.
Note: Do not save packages under Delphi/C++ Builder IDE.
