I created my first project on Google Code Project. The ksTools is a general purpose Delphi library. The initial checkin containes the TksComPort component for serial communication and the Terminal app to test the component. Both are for Delphi 2009 only. I am planning to add Delphi 2007 support and write some documentation later.
More details about the ksTools library are on the project page https://sergworks.wordpress.com/kstools
