As a software developer with more than twenty years experience specializing in terminal emulation software we've seen many competitors come and go. Freeware, shareware and open source terminal emulators have existed alongside commercial alternatives almost since the first terminal emulator was developed. While there are situations where they are perfectly suitable for a users needs, for those using terminal emulation in a commercial environment, they aren't a real option. Here's why.
One of the features of our flagship Windows Terminal emulator TTWin 4 is the wide range of terminal coverage that it offers. With more than 80 different terminals from a variety of manufacturers supported, we believe it's the most comprehensive package available. In our many years of producing terminal emulation software we've discovered the some terminals are, of course, more widely used than others and that certain terminals have become strongly associated with particular industries.
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.
