IVT has the following major features:

  • Multi-session, single-window. Tabbed interface.
    This means that your taskbar and desktop will not be cluttered-up by many windows when you have many simultaneous sessions.
    There are many ways within IVT to switch quickly between sessions (the tab bar being only one), and there is a statusline that keeps you informed about the activities of background sessions.
  • Multi-protocol. Supports SSH-2, Kerberized telnet, RLOGIN, NETBIOS and SERIAL protocols, all simultaneously. See these screen shots for examples.
  • Suited for environments with hundreds (or thousands) of machines. The address book of IVT can be shared on the network so multiple users can benefit from the groupings and descriptions.
    Project files allow further grouping of hosts.
  • The unique key broadcast script that comes bundled with IVT allows you to type at multipel hosts simultaneously. Ideal for making identical changes to multiple hosts (my personal record is making a change to 214 AIX machines simultanously).
  • Integration with Pageant, the PuTTY authentication agent. The SSH code in IVT is based on the freely available source of PuTTY. To this IVT adds multi-session, scripting, auto-login, host key management and automatic start of, and synchronisation with, Pageant. Users of the previous versions of IVT will also appreciate the many other powerful features of IVT.
  • HOSTLIST command to list and group your hosts with descriptive comments. Start a session with only a few mouse clicks.
  • Session-group editor (to launch a group of sessions with a single mouse click, login and start various commands on every session). Session groups can mix various types of sessions (SSH, Telnet, serial, etc).
  • Excellent support. If you have questions, require new features or find a bug, mail me and usually the problem will be fixed within days, if not hours.
  • Almost everyone I know who uses an emulator on a PC prefers IVT over other (commercial or freeware) alternatives.
  • Very accurate VT220 emulation, tested against the vttest program and real DEC hosts.

  • Variable sized windows, supports Telnet/SSH WindowSize messages.
  • Very flexible mouse support for X-terminal like cutting and pasting.
  • Powerful scripting language to automate just about every routine interaction with any host (such as logging in). Supports encrypting files for safe storage of passwords used during login.
    IVT is very suitable for batch processes on Windows machines that need to interact with some host. There are many features in the scripting language to deal with errors, timeouts, unexpected situations and so on.
  • Comes with a password-learning and auto-login system written in the IVT script language.
    This automatically learns your login procedure (user-id, password) and will automatically log you in the next time you connect to that host (if you want it to).
    Learning is configurable on a per-host and per-session basis. All learned passwords are stored in an encrypted file. Optionally, the passwords are kept in memory only and lost when IVT exits (for people who dislike stored passwords).
  • Excellent printer support (print screen, print session, print-through). Prints to files and to real printers, optionally in landscape, in full color, scaled to fit the paper in your printer.
  • Scroll-back memory (history). Text that has scrolled of the screen can be brought back (scrollbar and mouse-wheel support). History buffer can be any size.
  • Well over 600 pages of on-line, mouse-navigatable hypertext manual, (uses my own hypertext language implementation). HTML version of the manual is also available.
  • Context sensitive help that accesses the appropriate manual part instantly.
  • It's FAST. IVT outperforms all commercial and freeware terminal emulators I've looked at (quite a few).
  • X/Y/Zmodem file transfer. Auto Zmodem detection. File transfer can be over serial lines and/or SSH/Telnet sessions.
  • Lots more, but it is all in the manual pages.
