TN3270 4+

This app is not as good as it once was. An orange rectangle jumps around the screen as you touch it. You can zoom in, but not pan around. Very irritating.

I haven’t seen any of the bugs talked about in the poor reviews. It works well for the limiting situation of the iPad. It works well with a BT keyboard, and remember that the iOS interface for BT keyboards is problematic.

If you need basic 3270 support, especially if you’re doing a lot of ISPF editing, this is your app.

Disclaimer: I am an iPhone/iPad developer, but I am not affiliated in any way with MochaSoft. In fact, I might someday release my own competing TN3270 emulator. This post is neither a "shill" nor a "troll".

But I feel compelled to defend MochaSoft on the Bluetooth keyboard "issue" that was raised in another review. The fact is, this limitation is Apple's responsibility. The iOS keyboard interface does not provide any way for an app to capture the "enter/return" key — so there is NO WAY for TN3270 to treat it as the 3270 "enter" key!

As presently designed, the iOS keyboard interface passes only two things to the app: data keys and the backspace (delete) key. Nothing else — no "function" keys other than backspace are passed to the app. The app can configure the "enter/return" key to either (a) move the cursor to the next text input field, if there is one (similar to the 3270 "tab" function) or (b) dismiss the keyboard. But the app is not notified of either of these actions!
