Data Stream Trace
If enabled, PASSPORT creates a file called TRACE_xx.log. For example, if a data stream trace is being run for session A, the trace file will be called TRACE_41.log (xx is the session short name is converted to hexadecimal value). This trace captures the host data stream that is transmitted between the host and PASSPORT. This type of trace is very helpful in resolving problems involving the TN3270E SNA BIND attributes, file transfer, HLLAPI, and other problems involving the data stream.

Low Level Trace
If enabled, PASSPORT creates a file called TRACELL_xx.log. For example, if a low level trace is being run for session A, the trace file will be TRACELL_41.log (xx is the session short name is converted to hexadecimal value). This trace captures the lowest level of communication between the PASSPORT communications driver and the underlying communications subsystem. This type of trace is very helpful in resolving problems involving the establishment of a connection. This trace is not fully written to disk until the session is closed using either Connection>Disconnect or File>Exit.

HLLAPI Trace
If enabled, PASSPORT creates a file called EHTRACE.log. This trace captures the HLLAPI function calls made from a HLLAPI application program to PASSPORT. All inputs and outputs to each HLLAPI function call are written to this file. This type of trace is very helpful in resolving problems with HLLAPI applications.

FTP Trace
If enabled, PASSPORT creates a file called FTPTRACE_xx.log. This trace captures the FTP file transfer data when the
Transfer>Send or Transfer>Receive menu commands are used and FTP is chosen as the file transfer method. For example, an FTP trace file for session A would be named FTPTRACE_41.log.

This option does not affect the tracing of the PASSPORT FTP Client. To enable tracing of the FTP Client, first start the FTP client, then use the FTP Client Communications>Setup menu command, select the Settings tab, and enable low level trace. The trace file produced by the FTP Client is called FTPTrace.log.

Notes:
If PASSPORT session is in the connected state, you are only allowed to change the HLLAPI trace and FTP trace options. If PASSPORT session is disconnected you can change all four trace options and then click the
Connect button to start connecting to the host immediately.

When you disconnect the PASSPORT session using Communication>Disconnect and then reconnect using Communication>Connect the data stream and low level traces are rewritten. To avoid overwriting trace files rename the files, using Windows Explorer, to some other name before reconnecting the session.
