Problem connecting telit gm862 module with Python

P: 13
Hi all,

I have a telit EVK2 evaluation kit and a gm862 module. Setup was fine in my school computers and I was even able to write a small program to send and receive sms.

However when I brought it to my home computer, it gave warning messages like "The module is not responding. Do you want to retry to connect?" The funny thing is, the module can be detected in Hyperterminal. And I made sure to close off Hyperterminal when using Python so that the com port will not be busy.

Does anyone know why this is happening? Thank you very much for your attention.

For the benefit of anyone having the same problem, I found out that the problem lies with a faulty data cable. I was using a self-made rs232 cable and some of the wires got loose.

Though I don't quite understand why Hyperterminal works with a faulty data cable but PythonWin doesn't. Anyhow, if you have the same problem, try changing your data cables!
