What is a Terminal Emulator

In client/server computing a server is a large, powerful central computer. Servers are shared by many users who access it through remote input/output devices (keyboard/monitor combinations) that allowed the user to work with the remote computer. These are called terminals.

Originally such terminals were hardware devices. With modern end-user PCs becoming more powerful in the 1980's, these dedicated hardware devices were replaced by software that runs on a PC and which simulates features of the original hardware terminals. Such programs is called a terminal-emulator (a software that emulates/simulates a terminal).

About the PowerTerm Product Line

In its time, Ericom's line of PowerTerm emulators was an excellent terminal emulation software that was a fully functional user friendly windows based client/server application designed to interface with Telnet, Telnet-TLS/SSL, rlogin, and SSH servers located on UNIX style hosts. The software supported open source encryption software including Kerberos, OpenSSL, and OpenSSH.

Developed by Ericom Inc. until 2025, PowerTerm offered emulations like VT-100, VT-102, VT-220, VT-320, ANSI, ANSI-BBS, SCO-ANSI, QNX-2, IBM-3101, Televideo 925, Wyse 50, and XTERM terminals for as wide range of hosts IBM Mainframe, IBM AS/400, Unix, OpenVMS, and Data General, over network, modem or direct serial link from any PC.

Other features include customizable function keys, Power Script Language, multiple concurrent sessions, history scroll bar, menu bar, scalable and selectable fonts, intelligent copy function and more.

While it supported modern communication methods like SSH and Telnet/SSL, in later years the product had problems with the transition to newer versions of windows and featured an increasingly outdated user interface.

In March 2025 Ericom announced the End of Life for all PowerTerm products (PowerTerm Pro, PowerTerm Interconnect, PowerTerm Lite, ...).

While support will still be offered until 2027, now be a good time to transition to a modern and fully supported solution like ZOC Terminal.

ZOC Terminal as a PowerTerm Alternative

ZOC Terminal was started as a 32-bit software under OS/2 in 1995, which was about the same time of when the first PowerTerm product was started.

Over the years, ZOC has undergone many transitions. Offering a Windows implementation in 1999 was a step towards more propularity. Then offering a macOS version of ZOC in 2010 was another major step for ZOC.

Unlike Ericom's neglect and final quiet discontinuation, ZOC Terminal has been and still is under continued development for over 30 years nows. Unlike other solutions like PowerTerm, it still is in the hands of its original developers.

ZOC shares many features with PowerTerm Interconnect, e.g. superb VT220, Wy-50, but also a TN3270 emulations, as well as an extensive scripting language, and of course SSH, TLS, modem and telnet access to hosts.

But ZOC Terminal also offers modern features like tabbed sessions, a refined graphical user interface, secure shell connectivity and full support for modern operating systems like Windows 10/11 and macOS Sequoia.

In other words, if you are feeling the pain of PowerTerm sailing into the sunset, ZOC Terminal will offer an excellent alternative.
