Trace files contain records of internal activities on the TN3270 Service. These files describe events leading up to a difficulty and the exact state of the system when the difficulty occurred. Trace files are created when TN3270 Service tracing is enabled and then stored in the TRACES subdirectory of the TN3270 Service root directory with the filename extension TRC.

The following table describes the IBM terminal types supported by TN3270 Service.
