We have an app that copies files over a dialup connection using the copy file command. we are using dialup networking and the windows dialup server.
occasionally we get a "1104 - error reading file" during a copy operation over the dialout. We have a drive mapped to the share on the remote machine and are copying from the remove machines to the local machine where the app is running.

Has anyone had these problems? I'm guessing it has to do with line noise of some sort but don't know how to verify that or to stop it from happening.
