Displays detailed information about all TNA devices that exist on the local system. The information shown in the example is output for each TNA device. 2 PARAMETERS Displays current TELNET or TN3270 parameter settings. If you run multiple sessions, the display applies to the active session. DCL Format SHOW PARAMETERS UNIX Format display 3 Example TELNET> SHOW PARAMETERS Will flush output when sending interrupt characters Won't send interrupt characters in urgent mode Will map carriage return on output Won't recognize certain control characters Won't show option negotiation Won't print network data flow in hexadecimal [^^] echo [^]] escape [^?] erase [^O] flushoutput [^C] interrupt [^U] kill [^Y] quit [^T] areyouthere TELNET> Displays the parameter settings for the active session, revealing the following information: o Automatic flushing (AUTOFLUSH) of output is enabled. o Sending of interrupt characters in urgent mode (AUTOSYNCH) is disabled. o Mapping of received carriage returns (CRMOD) is enabled. o Mapping of carriage returns as Return LP on output (CRLF) is disabled. o Interpretation of control characters (LOCAL_CHARS) is enabled. The remote host does not recognize certain control characters; therefore, the local host interprets them. o Display of option negotiations (OPTIONS_VIEW) between the local and remote hosts is disabled. o The display or printing of data in hexadecimal (DEBUG) is disabled. Therefore, TELNET displays the data in readable text only. o The control characters are interpreted as listed. 2 SESSION Displays the session information about your current TELNET sessions (or TN3270 session) and, if you are running multiple TELNET sessions, about the waiting sessions. DCL Format SHOW SESSION UNIX Format status 3 Examples 1.TELNET> SHOW SESSION %TELNET-E-NOSESSION, No active session TELNET> CONNECT LUNA %TELNET-I-Trying, Trying... 192.1.2.3 %TELNET-I-SESSION, Session 01, host luna, port 23 -TELNET-I-Escape, Escape character: '^]' LUNA -- Unauthorized access is prohibited Username: BURNS Password: (password not echoed) Welcome to OpenVMS Alpha Version 7.3 on node LUNA $ (characters not echoed) TELNET> SHOW SESSION Session 01, host LUNA, port 23 (default active port) TELNET> Displays information about current sessions. The information returned for the first SHOW SESSION command reveals that the local host has no active sessions. The user then connects to host LUNA and returns to the TELNET prompt to display session information once again. This time, the SHOW SESSION command displays information about the connection with LUNA. 2.TELNET> CONNECT ESTRELLA 23 IBM-3278-2 . . . % (characters not echoed) TELNET> SHOW SESSION Session 01, host LUNA, port 23 Session 02, host ESTRELLA, port 23 (default active session) TELNET> Here, the same user has established another connection, this time to host ESTRELLA. The SHOW SESSION command displays information about all sessions, revealing that the current active session is with host ESTRELLA. 2 STATUS Displays the status of the current TELNET or TN3270 session and, if you are running multiple sessions, about the waiting sessions. Status information can include information about open sessions, such as which one is active and which ones are waiting, the escape character and options currently set, and the number of data overruns and suspended network I/Os (inputs/outputs) detected.
