I have tried adding a NDS3.0a modem for our 6150 phone. We are trying to get the phone to send SMSs via SDK3.0. At present however, we get a 7590 API error. When we go to the Phones & Modems settings in Control Panel, the Nokia GSM Data modem says that it is 'Non Functional'. what does that mean? I have tried adding/removing NDS3.0a/NDS3.0 and SDK3.0/SDK2.1, but to no avail.
We are running Windows 2000 Pro.
By the way, the phone 6100 appears in Nokia Connection Manager when we activate InfraRed on the Phone.
