Windows 7: Error 633:My modem is NOT busy,but windows says it is!

hi every one
When i dial up, i get some Error Message 633 message about COM port being used by other application or modem not configured properly.
In device manager the modem seems OK, and i dont know of any other device using a COM port. I've tried different drivers, swapping the modem around inside the case but no joy and i'm getting really annoyed now.
Any help would be much appreciated!

Hi and welcome

Com portrs can be used by old priinters, and a host of others things. when you go into device manager (type device manager in search) your device should be listed and not have a yellow triangle on it it should look like the pic

Let us know if you need help

Hi,

I was facing similar issue since last night. Just for your information, I am using Tata photon plus USB device to connect to internet on my lenovo thinkpad with windows 7 Home premium.
Now since yesterday evening the internet was working fine but then suddenly during night after a restart of system , I got this error 633 message. I tried my levels best to find a solution by searching every forum but alas got no luck. FInally I thought of giving "system restore" a try?
And BINGO ! it worked !!! so you guys whoever are facing this issue might think of giving "system restore" facility a shot and it might solve your problem? At least in my case it did. :-)

Regards,
