	The IBM 3270
		The 3270 is much more tightly coupled to the mainframe than a regular terminal would be.
		Up to 32 (?) 3270 terminals are connected via coaxial cable to a 3274 control unit, which in turn is connected (perhaps along with many other 3274s) to a mainframe I/O channel.
		At some point after the introduction of 3270 terminals, 3270 protocol converters began to appear, which allowed ordinary ASCII terminals to access 3270 applications by masquerading as 3274 control units to the mainframe and converting between 3270 datastreams and the escape sequences of the particular ASCII terminal.

	IBM 3270 from FOLDOC
		The 3270 attempts to minimise the number of I/O interrupts required by accepting large blocks of data, known as datastreams, in which both text and control (or formatting functions) are interspersed allowing an entire screen to be "painted" as a single output operation.
		A version of the IBM PC called the "3270 PC" was released in October 1983.
		tn3270 is modified version of Telnet which acts as a 3270 terminal emulator and can be used to connect to an IBM computer over a network.

	IBM 3270 PC / Large computer - Computerit-solutions.com
		IBM 3270 PC (type 5271), presented in October 1983, was strictly speaking an IBM PC XT, which however for the emulation of a terminal of the type IBM 3270 contained for the time of the publication the still necessary auxiliary hardware.
		So the 3270 PC both and usual single place computer could be used, and and terminals in the host terminal system.
		It corresponds to that 3270 PC, however on basis IBM PC RK in place of PC XT as basic model.

	TN3270 -- emulating an IBM 3270-class terminal (Site not responding. Last check: )
		Communicating with IBM mainframe applications requires the characteristics of an IBM 3270-class terminal.
		On the user side, since you do not have a 3270 keyboard, there needs to be a way to simulate pressing the special 3270 function keys that play a vital role in the interaction with IBM applications.
		With tn3270 this is accomplished by mapping certain keys or key combinations that are available on your keyboard to the special keys that are available on a 3270.

	RFC 1041 (rfc1041) - Telnet 3270 regime option
		Support for 3270 data stream requires that both sides: o be able to exchange binary data, o be able to put well defined delimiters into inbound/outbound data stream, o be able to establish the agreement between client and server on what type of terminal will be used.
		The purpose of this memo is not to describe (or define) protocols which are used in 3270 Regime, but rather define a new option for the Telnet Protocol, which would allow both sides to negotiate for the 3270 Regime establishment over the telnet connection.
		We also feel that such issues as keyboard mapping, whether to have one telnet for both ASCII and 3270 mode or two separate programs, one for ASCII and another for 3270 mode, are implementation dependent and should be considered as a local matter.
