Debugging a serial link is a specialized task.
- First, you must make sure that the other device works as expected.
You need a terminal software like
PuTTY[
^], and use it to sent commands and see the answers. Once it work as expected, go to next step.
- Second, check your software. You need a second computer with a serial port and the terminal software. Link both computers and run your program, you will on terminal what is send, then send an answer to your program.
If you can't establish communication with device, you need to make sure that all settings match.
Another problem can be the cable of the wrong type. There is mainly 2 types,
straight and
null modem, which can't be exchanged.
