But when i dial to that same number other modem i get access to internet. I have PS/2 mouse. And i have SoundBlaster Live value. So Live value is Irq 3 now. And i have Com1, Com3 now. My modem is Com4. So when i'm dialing other number than that internet number then my usb modem dials. So what i have to do?
