This function can change the system settings.
System settings are used to change the reading behavior of the handheld terminal.

Syntax

int SystemSetting(
  const char *option_string
);

Parameters

option_string: [in] Specifies a pointer to a system setting string.
For 2 characters, set as it is.
For 3 characters, add "[" to the beginning of the command.
For 4 characters, add "]" at the beginning of the command.
For 5 characters, add "{" at the beginning of the command.
For 6 characters, add "}" at the beginning of the command.

Return value

Returns OK if the function succeeds, ERROR otherwise.

Value	Description
OK	Option code is supported and set.
ERROR	Option code is not supported.

Remarks

Please refer to Barcode length settings and Barcode reader settings for available settings.
This function can support multiple commands specified in option_string at once.
For example, SystemSetting ("B0B2R4") allows you to read Code 39 and JAN.
The settings made by this API are not saved. Make the necessary settings each time you start up.
In addition, this setting reflects the setting changed by our menu bar code.
We recommend that you initialize it with U2 for the first time.
