A Error Messages

This section describes the error messages that might display on your terminal screen during a TN5250 session. These error messages are grouped into three categories:

◆Telnet errors

◆TN5250 internal errors

◆Status Line errors

Telnet Errors

Telnet errors are generated by Telnet communications software within a TN5250 terminal. These errors are related to initialization, start up, or connections during a session. They are normally due to operator error, incorrect command syntax, or network failures, and can usually be corrected by the system administrator. Table A-1 lists Telnet error messages.
