Disconnecting the device and reconnecting it does not solve this. Only way to get it to work is: Disconnect the modem, remove the SIM-card and put it into a cellphone, turn this phone on and off again, and put the SIM-card back in the modem. Now, when connected, the modem works. But nevertheless, this exact modem is floating around all over the internet, being sold everywhere…. Windows has a nasty habit of assuming thay anything connecter to a serial port at boot time MUST be a serial mouse and fires of a bunch of commands to it to the serial device.

Where did you buy it? I think this is a very, very old product from waaaay back when Wavecom made an unsuccessful attempt to get into the cellphone market?

It certainly does. Dave: Thanks for the clearance about WIndows behaviour at startup. ATZ does not work, however. The red light stays on, and the modem responds only to very few commands. Never seen that before… And it could not be used for anything, the computer said it could not find certain folders. So, waaay back? Sounds like this modem is quite obsolete, huh? I have now had the modem lying disconnected for a couple of days, but when connected again to a running computer it continues with the red light permanent on.

Seems a bit of long shot, but…. Anything you try to do with it is likely to be limited by its lack of capabilities. It might not even do GPRS…. What do you actually want to do with it. Do you really want a Modem - ie, a cased product - or an embedded module. And when the SIM-card is inserted into a normal cellphone, it start up instantly. No problem there. I have done it for a copuble of years using a Siemens TC35 which have done an excellent job.

So it did exist some time ago … maybe the SiWi team can trawl through the old Wavecom Archives that used to be available on the web and recover the AT commands guide for this device. As has been mentioned before, these things are for sale all over ebay and the internet in general….

Unfortunately, this is not an option. It is made for a security system, that must not depend on access to the internet. Hello all. However, are you using a Windows PC? You could try sending a atz to reset the modem after it has locked up. Ciao, Dave. It certainly does There are ways to disable this - google will help…. Hiya, Just to clarify: Should be You can tell that this is happening if you are getting random mouse movements on the screen.

Actually, I think you were right the first time? Again, it can be disabled…. Hello again. Thanks for the answers, everybody. But trying to disable this is worth the try. I fell like throwing in the towel, and get another GSM Modem. Can anybody recommend one? For another modem, have a look at the FXT range. Yes - very much so. Defnitely SIM operating voltages have changed a lot since this device was current. It might not even do GPRS… What do you actually want to do with it Do you really want a Modem - ie, a cased product - or an embedded module.

Hello again, davidc: Nope! It surely pre-dates USB by many years! As has been mentioned before, these things are for sale all over ebay and the internet in general… ciao, Dave. I got one. The thing is, it is not very stable. Nice one.
