cHandflow: Defines the flow control value.nStopBits: Defines the number of stop bits.cParity: Parity can be defined with one of these values: (E)ven, (O)dd, (M)ark, (S)pace, or (N)one.nDataLength: Defines a packet’s data length.A default value of 110 is used if no other value is provided.

nBaudRate: Defines the serial port baud rate.In the descriptions below, “n” indicates a numeric item and “c” designates a character item.

Serial port control information is presented as a string of 4 or 5 items, separated by a dash. Using the COM Port Status window in Serial Port Tester you can query the status of lines going to and from the computer. Consult documentation regarding making measurements through a serial port for detailed information regarding each setting. This may slow down messages slightly but will cause no further harm. If you don’t know the number of stop bits, you should set it to 2. The information you need to provide includes the number of serial ports to which your device is connected, its parity, the number of data bits per byte, and the baud rate. You will be entering this data into the serial port tester software prior to its use.

► Loopback Testing Using The HyperTerminal UtilityĬollect all the information that you can regarding the serial device you will be connecting to your machine.

Check the COM port due to loopback test.

When you are having difficulty obtaining data when using COM Port Tester (former Serial Port Monitor), try these steps: It provides RS232 tester software that allows you to gain insight into your serial communication to identify and fix com port errors. The question is "how to test a serial port?"ĭownload the Com Port Monitor application. You decide you might need to do some serial port testing. This is not acceptable and you think the issue is related to the RS232 communication. Data acquisition software has been installed but the expected data does not appear. You have just connected a serial device to your machine’s COM port.
