Why does ZTERMs FTP client display error code 12163?
ZTERM uses a part of Microsoft’s Internet Explorer to connect and transfer data using the FTP protocol. If you checked the “Work Offline” option on Internet Explorer’s File menu, this error will occur if you attempt to perform transfers via your local-area-network when you’re not connected to the Internet. The solution is to uncheck this option in Internet Explorer. Thanks to Peter Remick at Applied Micro Systems for pointing this out.
