I have an internal 56k fax modem by
3 Com Corp. When we try to use it, it
says that it is being used by another
dial-up network, or it says a modem cannot be detected, or the modem is not responding. No matter which message we get, we can go to the control panel and remove the modem and then add it again and use it once. But if you sign off you have to go throug it all again. Why?
