Member Type Documentation
enum QSerialPort::DataErrorPolicy
This enum describes the policies for the received symbols while parity errors were detected.
| Constant | Value | Description |
|---|---|---|
QSerialPort::SkipPolicy | 0 | Skips the bad character. |
QSerialPort::PassZeroPolicy | 1 | Replaces bad character with zero. |
QSerialPort::IgnorePolicy | 2 | Ignores the error for a bad character. |
QSerialPort::StopReceivingPolicy | 3 | Stops data reception on error. |
QSerialPort::UnknownPolicy | -1 | Unknown policy. |

Property Documentation
dataErrorPolicy : DataErrorPolicy
This property holds the error policy for how the process receives characters in the case where a parity error is detected.
If the setting is successful, returns true; otherwise returns false. The default policy set is IgnorePolicy.
Note: The serial port has to be open before trying to set this property; otherwise returns false and sets the NotOpenError error code. This is a bit unusual as opposed to the regular Qt property settings of a class. However, this is a special use case since the property is set through the interaction with the kernel and hardware. Hence, the two scenarios cannot be completely compared to each other.
Access functions:
| DataErrorPolicy | dataErrorPolicy() const |
| bool | setDataErrorPolicy(DataErrorPolicy policy = IgnorePolicy) |
Notifier signal:
| void | dataErrorPolicyChanged(QSerialPort::DataErrorPolicy policy) |
settingsRestoredOnClose : bool
This property holds the flag which specifies to restore the previous settings when closing the serial port.
If this flag is true, the settings will be restored; otherwise not. The default state of the QSerialPort class is to restore the settings.
Access functions:
| bool | settingsRestoredOnClose() const |
| void | setSettingsRestoredOnClose(bool restore) |
Notifier signal:
| void | settingsRestoredOnCloseChanged(bool restore) |
