A software serial number, otherwise called a product key, is usually not embedded in the software but is assigned to a specific user with a right to use the software. The software will function only if a potential user enters a valid product code. The vast majority of possible codes are rejected by the software.
Following is a list of code names that have been used to identify computer hardware and software products while in development. In some cases, the code name became the completed product's name, but most of these code names are no longer used once the associated products are released.
Product key on a Proof of License Certificate of Authenticity for Windows Vista Home Premium. A product key, also known as a software key, serial key or activation key, is a specific software-based key for a computer program.
Software flow control is a method of flow control used in computer data links, especially RS-232 serial. It uses special codes, transmitted in-band, over the primary communications channel. These codes are generally called XOFF and XON (from "transmit off" and "transmit on", respectively). Thus, "software flow control" is sometimes called "XON ...
Product activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it determines whether it is authorized to fully function. Activation allows the software to stop blocking its use.

At least some Morse code training software used a code key connected to the serial port to simulate actual code use; the status bits of the serial port could be sampled very rapidly and at predictable times, making it possible for the software to decipher Morse code. Serial computer mice may draw their operating power from the received data or ...
A software license is a legal instrument that governs the usage and distribution of computer software. [1] Often, such licenses are enforced by implementing in the software a product activation or digital rights management (DRM) mechanism, [2] seeking to prevent unauthorized use of the software by issuing a code sequence that must be entered into the application when prompted or stored in its ...
