Trying to set up a T-Mobile AudioVox 5600 with a USB connection to the computer is bringing up unfamiliar errors.

First, it initializes at 115200 (or something like that), and then I get this error:

"Error 800000018 from lineGetID"

The phone is set up with a USB connection, with the proper drivers installed. Anybody else figure this out?

Hi Alex,

I don't think that the Audiovox 5600 supports a GSM modem interface (at least not for being able to send/receive SMS).

The reason I say this is because it is based on Windows Mobile, and I have yet to see a Windows Mobile device that supports this capability.

While I expect that this device will not work, I'll go ahead and give the general troubleshooting advice that I would normally give to try to either get past the problem, or make a clear determination that the modem will not work.

The "Error 80000018 from lineGetID" message basically means that the Windows modem driver is unable to talk to the modem.

At this stage, all NowSMS is doing is asking Windows to open a connection to the modem. When you get this error, it either means that the Windows modem driver is not configured correctly, or another application is accessing the modem.

When another application is acessing the modem, the error is usually 80000048, but sometimes this 80000018 error is returned.

To get a better idea of what the problem is, I suggest going into the Windows Control Panel, Phone and Modem Options, select your modem, go into the Diagnostics area, and select Query Modem. See if Windows can talk to the modem, and if it can't, it may return a more descriptive error than NowSMS did.

If Windows can't talk to the modem, then either another application is already using the modem or the modem driver is not configured correctly.

Usually, if another application is already using the modem, you will see an error indicating that this is the case. If you have any other software installed with the modem (like a phone book utility), that software could be connected to the modem, and you need to exit that software. (Also, make sure that you have the NowSMS services stopped, as they could be connected to the modem.)

If it is a different type of error ... try rebooting to see if that makes a difference. Assuming it doesn't, then remove the modem driver and re-install it. The "Query Modem" function needs to be able to work successfully before NowSMS can have any chance of being able to talk to that particular modem driver.

If you only want to send/receive SMS, then you can try configuring NowSMS to talk to the modem directly over its COM port, instead of using a named modem driver. Even though the modem is USB (or Bluetooth), it is going to have a virtual COM port assigned to it by Windows.

(NowSMS needs to have a working Windows modem driver installed for the modem in order to send MMS over GPRS, but for SMS it can go direct to the COM port.)

If NowSMS can talk to the modem ok using the direct COM port reference, you can manually install a modem driver in Windows for the COM port that you are using. The "Standard 33600 bps Modem" driver is a good generic modem driver that you can manually install.

If you get past the modem initialisation issues, and NowSMS complains that the "Modem does not support SMS", then this indicates that the modem probably does not support the GSM modem commands related to SMS. (Which I expect is the case with the particular device you are trying.)

Sometimes this error can be returned with some devices when a PIN is required by the SIM, but a PIN was not specified in NowSMS. This is normally only an issue with dedicated modem devices, not phones acting as a modem. But if the SIM card has a PIN associated with it, it's a good idea to disable this if you are experiencing problems.

If you want to try to determine whether or not the modem actually supports the relevant commands, use HyperTerminal (Windows Start menu/Programs/Accessories/Communications) to connect to the COM port associated with the modem.

Type AT and press Enter, and you should get an OK back.

If the modem is not echoing back what you type, issue the command ATE1V1 (when I say issue the command, this means to type it in, and then press Enter).

Next, try the following SMS related commands that we use to test whether or not the modem supports SMS:

AT+CSMS=0
AT+CSMS=128

If both of the above return an error, then this suggests that the modem does not support SMS. However, to support some CDMA modems, in a recent patch of NowSMS, we will also accept an OK response to the following command (as long as it includes "+CSMS:" in the response to indicate that it really understood the command):

AT+CSMS?

Next, we need to see an OK response to one of the following commands:

AT+CMGF=0
AT+CMGF=1

If you see an ERROR response to all of those commands, then this would suggest that the device does not support the SMS related GSM modem commands defined in ETSI GSM 07.05 and/or 3GPP TS 27.005.
