dataComet-Secure X is an AppleScriptable Mac Telnet/TN3270 application offering full-featured color emulation of IBM 3279, DEC VT220, and PC-ANSI/SCO-ANSI terminals. Security is provided through SSH1/SSH2, SSL/TLS, and Kerberos 5 for Telnet & TN3270 connections.

Features include flexible and easy-to-use key remapping, macro script recording, integrated edit windows, modeless configuration dialogs, and SCP, ZMODEM and IND$FILE file transfer; modem and other serial connections can be used with the ASCII terminal emulators to access BBS.

What's New

Version 10.2.1r2:
  • Fixed a bug which caused dataComet to crash when "Scrollback Buffering" was turned on and the scrollback buffer was cleared, or the emulator window was resized.
  • DataComet should no longer crash if the dataComet "Preferences..." dialog panel is opened when no other windows are open.
  • The estimate of the current speed of file transfers in the File Transfer Progress dialog is now more accurate.


Mac OS X 10.3.9 or later
