With the Design Tool's trace feature, you can record data transmissions to and from the host. Although trace is intended primarily for diagnostic purposes, you can use the playback feature to redisplay the host's output to your screen. Playback does not redisplay the user's input.
Enter a file name for the trace in the File name box. By default the extension for trace files is .hst. Click Trace to begin the trace. To end the trace and close the file, click Connection, point to Datastream trace and click Stop trace.
