A software-based virtual serial port presents one or more virtual serial port identifiers on a PC which other applications can see and interact with as if they were real hardware ports, but the data sent and received to these virtual devices is handled by software that manipulates the transmitted and received data to grant greater functionality.
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 ...
Since the control signals for a serial port can be driven by any digital signal, some applications used the control lines of a serial port to monitor external devices, without exchanging serial data. A common commercial application of this principle was for some models of uninterruptible power supply which used the control lines to signal loss ...
In one form, product activation refers to a method invented by Ric Richardson and patented (U.S. patent 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to generate a unique installation ID.
A product key, also known as a software key, serial key or activation key, is a specific software-based key for a computer program. It certifies that the copy of the program is original. It certifies that the copy of the program is original.
A more innovative modern dongle is designed with a code porting process which transfers encrypted parts of the software vendor's program code or license enforcement into a secure hardware environment (such as in a smart card OS, mentioned above). An ISV can port thousands of lines of important computer program code into the dongle. [citation ...

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).
