Terminal emulation is a technology that evolved out of a need to replace the traditional hardware terminals used to connect to mainframe and host systems. At Turbosoft, we specialize in software based terminal emulation, mostly for Windows platforms and embedded systems. However historically there have been other solutions that have been developed to replace the original terminals.
ASCII and EBCDIC are two character encoding schemes which have played a historical hole in mainframe environments. Character encoding is simply a method of representing characters in data, morse code, for example is an early type of character encoding. This article takes a brief look at character encoding across modern and legacy systems.
We continue to look at standards, old and new, that have played a role in the evolution of terminal emulation. This articles discusses SNA and TCP and their roles in network communications.
As a developer of terminal emulation software we're acutely aware of legacy technologies and the role they have played and in the evolution of windows terminal emulator software. This article is the first in a series that takes a look at some of the standards, old and new, that have played a role in terminal history.
