Introduction to ZOC Terminal
ZOC is a professional, modern and well-established terminal emulator and telnet client and it is known for its configurability and outstanding user interface.

The purpose of the program is to let you access character based hosts using Secure Shell (SSH), telnet (rfc854), RS232/serial and many other means of communication. It can be used to connect to Unix/Linux hosts and shell accounts, BBS's, IBM mainframes (via TN3270 or TN5250), internet muds or devices attached to the serial port of your computer.

ZOC features tabbed sessions and extensive functions like a typed command history, scrollback, multiple window support and others. This makes it the ideal tool for people who repeatedly need to access text based shell accounts from a Windows or macOS platform. With ZOC's support for the Linux (Xterm) emulation, complete with 256 color support, meta-keys and local printing, Linux admins will feel as though they are sitting at their native consoles. Also, if you are working with the Cisco CLI this is your tool.

ZOC also supports Xterm, vt220 and several types of ansi as well as Wyse, TVI (Televideo), 3270, and Sun's CDE. ZOC also utilises all main file transfer protocols, including SCP, FTP, SFTP, FTPS, as well as X-, Y- and Zmodem, Kermit and many others. All of which are offered in a flexible and intuitive interface that leaves absolutely nothing to be desired.

With all the above features, ZOC also makes a good replacement for ProComm or for software like Attachmate, Ericomm PowerTerm, etc.

ZOC is also highly configurable. As well as the standard terminal features such as keyboard redefinition and scroll back buffer it also offers some more advanced and unique features including a powerful scripting language, and automatic triggering of actions based on received or typed text or a line trace feature.
