TCP/IP
Transmission Control Protocol/Internet Protocol is the de facto standard for Internet communications that is
widely used on local area networks. Technically, this means the TCP and IP protocols, but the term has come to
encompass all of the related protocols, such as TELNET, FTP, lpd, etc.
TCP Port
A method of accessing a TCP/IP service, where a device with a single IP address can have multiple TCP ports.
For example, TELNET is port 23, lpd is port 515, etc.; to access a service, you would specify the IP address of
the device plus the TCP port number of the service.
TCPware
A popular VMS TCP/IP software package sold by Process Software.
TELNET
A TCP/IP protocol that allows two devices to communicate over a LAN. One of the devices appears as if it were
a dumb serial terminal that is hardwired to the other device. TELNET is used by TROY print servers to allow
devices like PCs to access the print server remote console.
TELNET interpretation
In the TELNET protocol, certain characters are intercepted and handled in a special manner, rather than being
sent directly to the device.
