Error 775 on dial-up modem connection
Posted on 2013-02-02
I use a dial-up modem on occasions when our internet cable service experiences an interruption. Recently I have been unable to connect to our dial-up service provider, receiving an Error 775: The connection was blocked by the remote computer. However, I don't think that error is valid, because it appears so quickly after initiating the call (literally within two seconds) that the modem could not have finished dialing the number, to say nothing of connecting and having the call blocked. Our dial-up provider has a local telephone number as well as some long-distance numbers. Connecting to that service using one of the long-distance numbers works fine. It is just the local dial-up number which produces this error. This is an issue, because at times when I must rely on a dial-up connection, it would be expensive to use a long-distance telephone number, when a free local number is available. Recreating the dial-up connection, the same error appears. If I dial the local dial-up number with my voice phone, I hear normal modem tones on the other end. I suspect there is some setting or file which has become corrupted, returning Error 775 inappropriately.
