trace is installed.
The trace (log) function provides support for application development.
Usually this function is used only for debugging OPOS applications; it is
not used for other purposes.
On Windows 2000, Windows XP and Windows Vista, the user must
have the administrative permissions in order to use this function.
When EPSON CO is used, the log of all devices can be taken. When
CCO is used, only the log of POSPrinter, LineDisplay, CashDrawer,
MICR, CheckScanner and ElectronicJournal can be taken.
<OPOS API Trace setting dialog box>
"DeviceName" combo box
Use this combo box to select a device name for enabling the OPOS API
trace function.
The device is the target to use when "Private Trace" is selected.
If a device name is currently selected in the window, the device appears as
the default name in the combo box.
If the currently selected device's settings have been changed, changing
the settings of another device displays a message box to confirm to save
the settings. Select the [Yes] button to save the settings to the registry.
Even if the [Cancel] button is selected to close the dialog box, the settings
are not abandoned.
"Tracing mode" radio buttons
Select a tracing mode from the following options:
"No Trace"
: Disable the OPOS API trace function.
This option is selected as the default.
"Global Trace"
: Trace all OPOS devices (EPSON devices only).
"Private Trace"
: Trace only the specified valid device.
Usually, select "No Trace".
When the OPOS API trace is turned on, all OPOS API calls (all property
access and all method calls) are traced, with the trace result recorded in
the trace log file. Note that the "Global Trace" option takes priority over
the "Private Trace" option, but when the "Private Trace" option is used,
the "Global Trace" settings are deleted. For example, if "Global Trace"
has been set to the POS printer and the user uses the line display to set
trace to "Private Trace", the POS printer will be excluded from the target
