modem/com port problems

I'm having problems with a internal modem and the comm port it's on. When I go into control panel>modems>Diagnostics tab and click on more info it says it can't open the port.

The only thing I can come up with is that something is interfering with the port that I don't know about. As far as I can tell everything that is running should be using the port or modem.

Any ideas whats going on?

 

Hi Fabio,

Is this something that has just failed or have you installled something recently? Being as it is in internal modem it's only using a pseudo com port and is reliant on the modem driver. Have you tried the obvious - reinstalling the driver?

 

I had to install an old external modem to get on the net, it looks to be using the same exacxt driver as the internal.

I was told some freeware programs were installed before the modem went kaput. I don't think some dinky little spyware program could knock out a modem. Have had no virus alerts either.

 

Have you tried completely removing the modem both physically and from the device manager, then reinstalling physically and then allowing windows to redetect on reboot?

It still sounds like an incorrect driver.

 

Well I ended up removing the modem physically from the computer and reinstalled everything.

For some reason the modem is now on COM4 now even though it's back it the same slot. no big problem though.

thanks
