*Conan The Librarian
The TELNET port driver (TNDRIVER) provides terminal session support for TCP stream connections using the RAW, NVT, RLOGIN, and TELNET protocols. Either a remote device or an application can be present at the remote endpoint of the connection. A user program can manage a TELNET connection with the standard OpenVMS $QIO system service by using the IO$_TTY_PORT and IO$_ TTY_PORT_BUFIO I/O function codes. This section describes these I/O function codes and their associated arguments.
