Hello Mike,

The log indicates that there is a problem with the (virtual) serial port driver of the modem pool or with the modem module itself. It triggers a response timeout after the 'AT+CMGR' command that is sent to the modem to get the revision number of the firmware software. The modem identifies itself as a two band modem, that means that the modem module is not a Q24plus module but probably an older Wavecom compatible module like the Q2303A.

You can try to ignore the error an proceed with the setup procedure, it is possible that the modem works fine. However, it is likely that the modem does not work reliably after it is setup. You can try if changing one of the following setting in the advanced properties of the GSM Modem Gateway settings makes any difference:

- Set the 'FlowControl' property to 'None' or 'XonXoff'.
- Set the 'CompatibilityMode' property to 'BasicPDUMode'

If that does not help then the only solution might be to update the firmware of the modem pool or exchange the modem modules of the modem pool to another module type.

Regards, Henk

Can you please help/advise,

I have installed the drivers and Windows has configured 16 USB virtual ports for the Wavecom module. I have then installed Diafaan light but I am unable to complete the set up of a GSM Modem Gateway.

In the drop down menu for the "GSM Modem" the wavecom modems are listed on various com ports but I am unable to obtain a successful modem test on any of the modems listed here. Every test FAILS.

I have installed 1 GSM sim into the module unit. This sim is on vodafone UK network. The sim is NOT configured with any PIN as I have checked this with the sim installed into normal handset.

The GSM modem details displayed on the gateway set up are shown as follows:
Port: COM23:115200,n,8,1
Manufacturer:WAVECOM MODEM
Model: MULTIBAND 900E 1800

Here is a copy of a modem test (failed):
- Open port: COM23:115200,n,8,1
> AT&FE0



< MULTIBAND 900E 1800

- Timeout
- Port closed

Thanks in advance
