Detailed Description¶
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
Use the static
availablePorts()
function to generate a list ofQSerialPortInfo
objects. EachQSerialPortInfo
object in the list represents a single serial port and can be queried for theport name
,system location
,description
,manufacturer
, and some other hardware parameters. TheQSerialPortInfo
class can also be used as an input parameter for thesetPort()
method of theQSerialPort
class.Example Usage¶
The example code enumerates all available serial ports and prints their parameters to console:
serialPortInfos = QSerialPortInfo.availablePorts() for portInfo in serialPortInfos: print("\n") << "Port:" << portInfo.portName() << "\n" << "Location:" << portInfo.systemLocation() << "\n" << "Description:" << portInfo.description() << "\n" << "Manufacturer:" << portInfo.manufacturer() << "\n" << "Serial number:" << portInfo.serialNumber() << "\n" << "Vendor Identifier:" << (portInfo.hasVendorIdentifier() ? QByteArray.number(portInfo.vendorIdentifier(), 16) : QByteArray()) << "\n" << "Product Identifier:" << (portInfo.hasProductIdentifier() ? QByteArray.number(portInfo.productIdentifier(), 16) super().__init__())

- __init__()¶
Constructs an empty
QSerialPortInfo
object.See also
- __init__(port)
- Parameters:
port –
QSerialPort
Constructs a
QSerialPortInfo
object from serialport
.- __init__(other)
- Parameters:
other –
QSerialPortInfo
Constructs a copy of
other
.- __init__(name)
- Parameters:
name – str
Constructs a
QSerialPortInfo
object from serial portname
.This constructor finds the relevant serial port among the available ones according to the port name
name
, and constructs the serial port info instance for that port.- static availablePorts()¶
- Return type:
.list of QSerialPortInfo
Returns a list of available serial ports on the system.
- description()¶
- Return type:
str
Returns the description string of the serial port, if available; otherwise returns an empty string.

- hasProductIdentifier()¶
- Return type:
bool
Returns
true
if there is a valid16-bit
product number present; otherwise returnsfalse
.- hasVendorIdentifier()¶
- Return type:
bool
Returns
true
if there is a valid16-bit
vendor number present; otherwise returnsfalse
.- isNull()¶
- Return type:
bool
Returns whether this
QSerialPortInfo
object holds a serial port definition.- manufacturer()¶
- Return type:
str
Returns the manufacturer string of the serial port, if available; otherwise returns an empty string.

- Return type:
str
Returns the name of the serial port.
See also
- productIdentifier()¶
- Return type:
int
Returns the 16-bit product number for the serial port, if available; otherwise returns zero.
- serialNumber()¶
- Return type:
str
Returns the serial number string of the serial port, if available; otherwise returns an empty string.

.list of qint32
Returns a list of available standard baud rates supported by the target platform.
- swap(other)¶
- Parameters:
other –
QSerialPortInfo
Swaps
QSerialPortInfo
other
with thisQSerialPortInfo
. This operation is very fast and never fails.- systemLocation()¶
- Return type:
str
Returns the system location of the serial port.
