This would be difficult insofar as not all Windows OSes have telnet by default. &nbsp;If you were to find some way to distribute it, or make it a prerequiste for using your application, you could certainly call it from within your application.

That would also be blocked by any firewall. &nbsp;Incoming connections are usually blocked unless you specifically open the port for it.

test connectivity for tcp application

Microsoft applications include a variety of software programs, including development and digital authoring programs (Expression and Media Center), educational programs, Internet software, including Essentials, Skype and the Live family, anti-virus, productivity applications and suites like Office, Excel, Word, Outlook, Access and PowerPoint, video games and server applications such as Exchange, SharePoint, IIS and Virtual Server.

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
