The UpFront ratlog.txt file appears in the UpFront directory every time you run UpFront. It will always contain a certain amount of logging information. In particular it will make a log of the telnet negotiation between UpFront and the host computer.

The amount of information logged cab be increased using two seperate dialogs. The main dialog is selected via the "Options - Diagnostics ..." pulldown menu and looks like:-

This allows logging of the "MWS" protocol that drives UpFront and also allows you to debug any events you have set up in UpFront (e.g. if you a have a script attached to an event such as clicking on a field). The receive filter allows you to filter the protocol logging against a regular expression which can be helpful in tracking messages about particular fields. In particular if you are having problems with keyboard mapping you can see what pf key UpFront is sending by looking at the protocol messages sent ("X451261" means pf key 1).

The above diagnostics can be supplemented by the "Alex" diagnostics dialog. "Alex" is the language that much of UpFront was developed in. The "Alex" dialog is seen if you keep the shift key pressed when starting UpFront from an icon. It looks like this:-

Most of these check boxes should not be used unless asked for by UpFront support. The "Comms" loggin though provides a detailed log of all communciation between UpFront and the host. This can be invaluable in diagnosing issues with the terminal emulator.
