Appendix D. Basic Diagnostics

Windows utilities and administration commands can serve as basic independent diagnostics that help debug
problems relating to Serial/IP Redirector installation or configuration of the serial server.

Use "ping" to Check the Network Connection

Ensure that the PC is connected to the server using the Microsoft TCP/IP networking software supplied with
Windows. Open a DOS command prompt window and type in the ping command, using the server's network
address or domain name in place of the xxx.xxx.xxx.xxx:

C:\ ping xxx.xxx.xxx.xxx

The output should indicate that ping has reached the server. If not, the Serial/IP Redirector will not be able to use
the server until the problem is resolved. Contact your system administrator for help.

Use "route" to Check the Routing Table

If there is more than one default route, the Serial/IP Redirector may not be able to determine a correct static route
to the server and will display a warning dialog. Follow this process:

Check the PC's route table for multiple default routes. Open a DOS command prompt and use the route print
command:

C:\ route print ...

(multiple lines of output showing the routes

in effect)

The output will indicate if there is only one default route. In the command's output, the default routes appear at
the top and show a Network Address value of 0.0.0.0. If the PC has more than one default route, the Serial/IP
Redirector may not be able to access a server that is not on the same subnet.

In Windows XP, NT and 2000, make sure you are logged into an account with administrator privileges. Use the
Windows NT User Manager or check with your system administrator if you are not sure of the status of your
current account.
