To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:

1. If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port.
2. Take a metal paperclip or wire and cross pins 2 and 3. If you look closely at the female end, the pins should be numbered.
3. Open a telnet session on the COM port number of the device that you are testing. To find out the COM port number, refer to the following FAQ: https://www.startech.com/faq/com-port-listing-windows.

It is difficult to test the adapter, as so many things are involved, but you can test the Pi serial port. You can check functionality without any external hardware. Connect GPIO pins 8-10 which will cause an external loopback. Running a serial application on the Pi and you should see the output echoed back. Serial Loopback Test v.1.10 This application runs a loopback test of the selected serial port. /nokia-6151-unlock-code-free.html. The user must simply connect the TX and RX signal lines and then execute the test. File Name:SerialLoopbackTestSetup110. I want to perfrom loopback test on serial port using a loopback connector. I need to write a code using qt 4.7.4. But I am totally new to serial port programming. I am not supposed to use minicom or any 3rd party software. Is it possible to do this using script?? Echo 'hello' /dv/ttyS0 and cat /dev/ttyS0 /root/temp.txt work?? To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following: If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port. Take a metal paperclip or wire and cross pins 2 and 3. With the help of a serial loopback test software, users can identify problems in their serial port, cable connection, or the software that generates the messages without needing to connect with third-party hardware. The use of loopback tests is to confirm proper RS232, RS422, and RS485 serial communications.

Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. nexus 10 user manual download Windows XP comes with Hyper Terminal.

4. When the session is open, anything you type into it you should see. The loopback test fails when you cannot see what you are typing.

If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port.

You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.
