Default: /NOTIMEOUT o /TIMEOUT< Creates a TNA device that has the following connection attributes:C - NOIDLE-The connection is broken when the device is finallyA deassigned. The device will automatically reconnect when data is written to it.C - IDLE-Specifies the idle time for the device. If the device@ is idle for at least the specified amount of time (noteA that the time has a granularity of one second), then theB connection will be broken. Idle means that the devi ce has@ neither received nor sent any data for the idle period.? - NORECONNECTION-The device does not automatically retry$ reconnections if they fail.< - RECONNECTION-When data is written to the device and? the device is not connected, this value determines the@ interval between reconnection attempts. For example, ifC an application writes to a TNA with a RECONNECTION-0:1:00,C and if the first connection attempt fails, then subsequent@ connection attempts will be made in 1-minute intervals.  o /NOTIMEOUT> Creates a TNA device that breaks the connection when the? device is finally deassigned (the last channel assignment is deassigned). /PERMANENT Optional.< Creates a TNA device that disconnects on deassignment and reconnects on assignment. /PROTOCOL /PROTOCOL=options, Optional.

(Usually, Go Ahead is suppressed, so sending a GA has no effect.) DCL Format SEND GA UNIX Format send ga 2 IPC SEND IP (Interrupt Program) interrupts the execution of the lastB command you entered on the remote host. The interrupt characterC clears the input and output paths to the remote host. The remoteD host interrupts the program that is processing. (This command has no effect in binary mod<e.)C Use this command if either your terminal or the remote host does9 not recognize the default interrupt character, Ctrl/C. DCL Format SEND IP UNIX Format send ip 2 NOP@ SEND NOP (No Operation) tells you whether your local host canC send data to the remote host and the remote host can receive the data. If you:B o Get an %TELNET-E-INETERROR error message, there is a problemA with the connection; the remote host is not able to rece=ive data.D o Get an %TELNET-S-REMCLOSED status message, the connection with& the remote host has been closed.< o Do not get an error message, the connection is active. DCL Format SEND NOP UNIX Format send nop 3 Examples' 1.% (characters not echoed) TELNET> SEND NOP 5 %TELNET-I-SESSION, Session 01, host nyx, port 23> No error message indicates the connection is active.

The SYNCH is sent in= urgent mode (out-of-band, OOB). As a result, the following act ?ions occur:> 1. The local host immediately sends an interrupt character,C placing it at the front of the data stream sent to the remote host.D 2. The remote host immediately processes the interrupt character,< ignoring any incoming data not yet processed, and then? including a TELNET synchronization or interrupt character9 in the data stream it sends back to the local host.? 3. The local host throws away all incoming data (rather thanC processi@ng that data) until it detects the synchronization orD interrupt character. This provides faster response time to the/ synchronization and interrupt characters. DCL Format SEND SYNCH UNIX Format send synch wwWUvĩ1 SET 2 ECHO Sets the echo character.@ Use this command if either your terminal or the remote system; does not recognize the default echo character. Enter the$ following sequence of characters:%A 1. Opening quotation marks 2. A circumflex ( ^ ) 3. The new echo character 4. Closing quotation marks DCL Format SET ECHO "^character" UNIX Format set echo "^character" 3 Parameters "^character" Required.3 Character you want to use as the echo character. 3 Example TELNET> SET ECHO "^m" Echo character is '^M'.6 Sets the echo control character to either m or M. 2 ERASE Sets the erase charBacter.D The erase character deletes, either locally or remotely, the lastD character in the type-ahead buffer. (This character has no effect in binary mode.)@ Use this command if either your terminal or the remote systemB does not recognize the default erase character, the Delete key.. Enter the following sequence of characters: 1. Opening quotation marks 2. A circumflex ( ^ ) 3. The new erase character 4.

When youD run multiple sessions, you can set different escape sDequences for each connection.@ Use this command if either your terminal or the remote systemA does not recognize the default escape character, Ctrl/]. Enter( the following sequence of characters: 1. Opening quotation marks 2. A circumflex ( ^ ) 3. The new escape character 4. Closing quotation marks DCL Format SET ESCAPE "^character" UNIX Format set escape "^character" 3 Parameters "^character" Required.E5 Character you want to use as the escape character. 3 Example TELNET> SET ESCAPE "^P" Escape character is '^p'.8 Sets the escape control character to either p or P. 2 FLUSHOUTPUT# Sets the flush output character.C Use this command if either your terminal or the remote host does< not recognize the default flush output character, Ctrl/O.. Enter the following sequence of characters: 1. Opening quotation marks 2. A circumflex ( ^ )$ 3. "FThe new flush output character 4. Closing quotation marks DCL Format" SET FLUSHOUTPUT "^character" UNIX Format" set flushoutput "^character" 3 Parameters "^character" Required.; Character you want to use as the flush output character. 3 Example TELNET> SET FLUSHOUTPUT "^P" Flush output character is '^p'.> Sets the flush output control character to either p or P. 2 INTERRUPT Sets the interrupt character.G? The interrupt character clears the input and output paths toB the remote host. The remote host interrupts the program that is= processing. (This character has no effect in binary mode.)C Use this command if either your terminal or the remote host does9 not recognize the default interrupt character, Ctrl/C.. Enter the following sequence of characters: 1. Opening quotation marks 2. A circumflex ( ^ )! 3. The new interrupt character 4. Closing quotatio"Hn marks DCL Format SET INTERRUPT "^character" UNIX Format set interrupt "^character" 3 Parameters "^character" Required.8 Character you want to use as the interrupt character. 3 Example TELNET> SET INTERRUPT "^a" Interrupt character is '^A'.; Sets the interrupt control character to either a or A. 2 KILL Sets the kill character.> The kill character discards, both locally and remotely, theD entire tyIpe-ahead buffer. (This character has no effect in binary mode.)C Use this command if either your terminal or the remote host does4 not recognize the default kill character, Ctrl/U.. Enter the following sequence of characters: 1. Opening quotation marks 2. A circumflex ( ^ ) 3. The new kill character 4. Closing quotation marks DCL Format SET KILL "^character" UNIX Format set kill "^character" 3 Parameters "^chJaracter" Required.3 Character you want to use as the kill character. 3 Example TELNET> SET KILL "^q" Kill character is '^Q'.6 Sets the kill control character to either q or Q. 2 MODE! Sets the mode of transmission.@ The mode of transmission can be either character mode or lineC mode. Character mode is the default. Use character mode when youB run a character-processing text editor on the remote host. With@ character mode, your local system s Kends data a character at aC time to the remote host with which you have a connected session,@ and the remote host echoes the characters back for display onB your local system. (Sometimes several characters may be sent inA a burst for performance optimization, in which case the remoteC server usually replies with bursts of characters, but not a line at a time.)C To use line mode, the remote host server must support line mode.D The local host echoes characters. Line mode aLllows the following:A o Signal trapping (such as for application programs on remote4 UNIX hosts that sense traps or special events) o Local character editing< o Tab expansion (where a tab is more than simply the TAB character)9 This command overrides the ENABLE LOCAL_CHARS command.@ Before you enter this command, establish a remote connection. DCL Format SET MODE {CHAR | LINE} UNIX Format mode mode 3 Parameters !M CHAR LINE Required.; Transmission mode you want to set. Specify either of the following:9 o CHAR - Data is transmitted one character at a time.4 o LINE - Data is transmitted one line at a time. 2 QUIT= Sets the quit character, an alternate interrupt character. DCL Format SET QUIT "^character" UNIX Format set quit "^character" 3 Parameters "^character" Required.3 Character you want to use as the #Nquit character. 3 Example TELNET> SET QUIT "^i" Quit character is '^I'.B Sets the alternate interrupt control character to either i or I. 2 TERMINAL= Sets the default terminal type for future TELNET or TN3270 connections. Format SET TERMINAL /DEVICE=type 3 Qualifiers /DEVICE /DEVICE=type Required.0 Terminal model. Specify one of the following: o A terminal model.B o An IBM terminal to emu!Olate.
