I've been trying to configure my 8100 to act as a modem for my laptop for 4 hours now without success. 2 calls to T-mobile were not helpful either. Error code 692 persists.

There was no default "standard modem" available after installing the Blackberry Desktop Manager, so I created one using the RIM virtual serial port. I configured the modem to have the extra initialization string <+cgdcont=1,"IP","wap.voicestream.com"> and ran the diagnostic, which returns:
<ATQ0V1E0 - OK
AT+GMM - BlackBerry IP Modem
AT+FCLASS=? - COMMAND NOT SUPPORTED
AT#CLS=? - COMMAND NOT SUPPORTED
AT+GCI? - COMMAND NOT SUPPORTED

I created a new internet connection, specifying "*99#" as the number to dial. I have the desktop manager open (it displays connected) and when I dial I get error code 692. Any help would be greatly appreciated. Thanks in advance.

Cheers
