VPortPro makes serial (RS232) data from your PC available on TCP/IP-based networks and makes TCP/IP data available on virtual serial ports of your PC. Visit Home of VPortPro for more information.



Trace Settings

The tracing utility is designed for setting a number of trace flags (by toggling related check boxes to filter out data of your interest) and passing them to the virtual serial port driver. According to the Trace Flags set, utilities of the package will filter out and save related information into corresponding trace files you can analyze later. The tracing could be used to document the virtual serial port traffic between your software applications that communicate with serial servers via connection channels.

Normally, users should not arbitrarily turn on/off Trace Flags. The flags can noticeably slow down the traffic and can generate a great amount of data. The tracing utility is primarily meant for testing and analyzing how your virtual serial port software applications interface to access servers while using serial port communication features.


Driver Tracing Settings

You can start the tracing program by clicking the Trace driver button in the Advanced dialog box. The COM Port Redirector Driver Tracing window will appear on your display:

In this window, the program displays event tracing information according to trace flags you specified for the virtual serial port driver in the Trace Settings dialog box described below. The information displayed will also be saved in a log file (if specified in the Trace Settings dialog box).

Pressing Exit on the menu bar closes the window and exits the program.

Pressing Settings on the menu bar brings up the Trace Settings dialog box. (Refer to section Making Trace Settings below.)

Pressing DumpFile on the menu bar brings up the Dump File dialog box. (Refer to section The Dump File Box below.)

Pressing Trace on the menu bar brings up a submenu where you can choose to start or stop tracing.


Making Trace Settings

Pressing Settings on the menu bar of the COM Port Redirector Driver Tracing window brings up the Trace Settings dialog box:

If you click the Close button, the program closes the dialog with no changes.

Pressing the Apply button passes the Trace Flags set to the virtual serial port driver. The Trace Flags will take effect immediately.

Select All makes all the Trace Flags enabled. Clear All makes all the Trace Flags disabled.

Refresh restores all Trace Flags to their initial states (when loaded the tracing utility or after the latest Apply).

With the Save to use in next sessions check box enabled, you can store the current settings (by pressing Apply) and load them later (when loading the tracing utility).

With the Write trace data to log file check box enabled, you can enter a full path file name or leave the default one in the Log File field to store flagged log information into that file.


The DumpFile Box

Pressing DumpFile on the menu bar of the COM Port Redirector Driver Tracing window brings up the dialog box:

You can specify a full path name for one of system dump files to be read (when system crash) and a log file name to store the driver tracing information extracted from that dump file that you can analyze later. Normally, you can use the default file names shown.
