Carnation Software has released MacWise 12.11 (http://www.MacWise.com) for Mac OS X 10.2 and higher. It fixes a problem in which you couldn’t select Transparency from the Window Menu.
Many host computers are programmed to instruct the client app to save and restore screens. MacWise 12.0 or later supports three sets of escape sequences commonly used by PC clients (HostAccess, Accuterm and System Builder).
The software emulates ADDS Viewpoint, Wyse 50, Wyse 60, Wyse 370, Televideo TV 925, DEC VT100, VT220 and Prism terminals. MacWise also supports ANSI and SCO ANSI color. Esprit III color is also supported in Wyse 370 mode, and AppleScript. It works with Intel or PowerPC Macs, MacBooks, Powerbooks and desktops and allows users to connect to the host via serial, modem, telnet, ssh, via the internet or local connection.
MacWise costs US$95 for a single users license. Version 12.11 is a free upgrade for registered users of version 12.x.
