Recovering From Errors
You can apply the following general approach to recover from errors that you receive
on your terminal screen while using TELNET with the Telserv Product.

Make sure that the command you have entered has valid parameters, such as the
host name or address, the user name or ID, or the port number. Some errors result
from a simple typing mistake. If you have made a typing error, try the command
again. If the error is more complicated, you can ask your system administrator for
help in locating the problem. If necessary, you can also contact the system
administrator of the remote system.

Communication problems that result in socket error messages can occur. These
error messages include an error-reason that is returned. To find a complete
explanation of these errors, refer to the TCP/IP Programming Manual. The
descriptions of file-system errors in the Guardian Procedure Errors and Messages
Manual also include some error-reason values you might encounter, as well as
the error-number values listed in some messages.

In some cases, errors occur because the TCP/IP process is no longer running. Ask
your system administrator to check whether the TCP/IP process has stopped.
