set (serial) (MATLAB Function Reference)

Configure or display serial port object properties

Syntax

set(obj)
props = set(obj)
set(obj,'PropertyName')
props = set(obj,'PropertyName')
set(obj,'PropertyName',PropertyValue,...)
set(obj,PN,PV)
set(obj,S)

Arguments

obj
A serial port object or an array of serial port objects.

'PropertyName'
A property name for obj.

PropertyValue
A property value supported by PropertyName.

PN
A cell array of property names.

PV
A cell array of property values.

S
A structure with property names and property values.

props
A structure array whose field names are the property names for obj, or cell array of possible values.

`obj`	A serial port object or an array of serial port objects.
`'PropertyName'`	A property name for `obj`.
`PropertyValue`	A property value supported by `PropertyName`.
`PN`	A cell array of property names.
`PV`	A cell array of property values.
`S`	A structure with property names and property values.
`props`	A structure array whose field names are the property names for `obj`, or cell array of possible values.

Description

set(obj) displays all configurable properties values for obj. If a property has a finite list of possible string values, then these values are also displayed.

props = set(obj) returns all configurable properties and their possible values for obj to props. props is a structure whose field names are the property names of obj, and whose values are cell arrays of possible property values. If the property does not have a finite set of possible values, then the cell array is empty.

set(obj,'PropertyName') displays the valid values for PropertyName if it possesses a finite list of string values.

props = set(obj,'PropertyName') returns the valid values for PropertyName to props. props is a cell array of possible string values or an empty cell array if PropertyName does not have a finite list of possible values.

set(obj,'PropertyName',PropertyValue,...) configures multiple property values with a single command.

set(obj,PN,PV) configures the properties specified in the cell array of strings PN to the corresponding values in the cell array PV. PN must be a vector. PV can be m-by-n where m is equal to the number of serial port objects in obj and n is equal to the length of PN.

set(obj,S) configures the named properties to the specified values for obj. S is a structure whose field names are serial port object properties, and whose field values are the values of the corresponding properties.

Remarks

Refer to Configuring Property Values for a list of serial port object properties that you can configure with set.

You can use any combination of property name/property value pairs, structures, and cell arrays in one call to set. Additionally, you can specify a property name without regard to case, and you can make use of property name completion. For example, if s is a serial port object, then the following commands are all valid.

set(s,'BaudRate')
set(s,'baudrate')
set(s,'BAUD')

If you use the help command to display help for set, then you need to supply the pathname shown below.

help serial/set

Examples

This example illustrates some of the ways you can use set to configure or return property values for the serial port object s.

s = serial('COM1');
set(s,'BaudRate',9600,'Parity','even')
set(s,{'StopBits','RecordName'},{2,'sydney.txt'})
set(s,'Parity')
[ {none} | odd | even | mark | space ]
