TN3270 from Aton International brings terminal emulation to Pocket PCs. The updated version includes a number of new features including a soft keyboard. TN3270 can be used to get at the "mainframe green screens" or to develop .NET applications that use communication protocols underneath. If you'd like to reach OS/400, CICS, VM/CMS or MVS directly from your Pocket PC, then this is for you! Price is $49.95 per single copy and there is a free 14 day trial version.
"The new version adds ease of use features including full screen landscape mode, new soft keyboard (pictured at right), and �on the fly� session switching that allows access to both mainframe and web services data without having to exit a program or reset the device. The package combines a .NET component with a user interface that looks like the screen of a TN3270 terminal."
