No Timeout event

[henry64]

Why doesn't any of the error events get fired when there are a timeout on initialization of the GSM modem?

I need this to ensure that the device is online and ready when the applications is started.

Hello

You can try to play with serial port control lines before activate GSM component.
See following methods (Signals demo)
  nrComm1.SetStateDTR();
  nrComm1.SetStateRTS();

Also we used following algorithm in MyGsm application:
1) Open serial port.
2) Send string AT#13
3) Wait reply. If reply is 'OK' activate TnrGsm class for target serial port.

Yes, sure I can play around and patch something together - but my question is, why doesn't any of error events fire where there is a timeout error?

If you already are using some workarounds in myGSM then - could you please publish the code or implement it in gsmdemo.
Did you receive my "updated" GSM demo, I have sent it to you by mail?

Hello

Yes, we have received your email. thank you for your information. We are analyzing LOG files and will try reproduce and resolve troubles.

Also You asked about closing event on usb plug off. Please try OnClose event in TnrComm component.

About sources of MyGSM.
We can not publish full sources.
We can post partial class that monitors serial port list and states of target ports, but we need time to prepare such sample.

I'm not asking for full source  :)

I just would like to see what you are doing regarding opening and closing the GSM device, you mentioned you was doing something else that the "simple" method.
       nrGsm.Active := True;
       nrComm.Active := True;

I forgot to mention that I would appreciat that  ::)
