Configuring Communication Settings

Before you can write or read data, both the serial port object and the device must have identical communication settings. Configuring serial port communications involves specifying values for properties that control the baud rate and the serial data format. These properties are given below.

Table 8-4: Communication Properties 

Property Name	Description
BaudRate	Specify the rate at which bits are transmitted
DataBits	Specify the number of data bits to transmit
Parity	Specify the type of parity checking
StopBits	Specify the number of bits used to indicate the end of a byte
Terminator	Specify the terminator character

Note    If the serial port object and the device communication settings are not identical, then you cannot successfully read or write data.

Refer to your device documentation for an explanation of its supported communication settings.
