1. The SeaLINK serial server’s IP address is not on the same subnet as the PC. 2. The route to the server’s address is handled via a "default" route. A default route is one with a network address of 0.0.0.0. © Sealevel Systems, Inc. - 58 - SeaLINK User Manual...
Page 61 This guarantees that the server will be accessible even if the default route changes. © Sealevel Systems, Inc. - 59 - SeaLINK User Manual...
