Overview

Appendix B points out basic problems that can occur when operating a 3800Plus modem. Use Tables C-1 through C-6 to check out these problems. If you are having data communication difficulties, such as periodic

character loss, random errors, or constant format errors, use the loopback tests described in Chapter 7, Test Branch. With these tests you can usually isolate the fault in your system by using the process of elimination. If problems continue to occur, contact your service representative.
