1 SEND 2 AO SEND AO (Abort Output) aborts the output of the last remote command you entered, while the command continues to execute. If you issue another SEND AO, the output resumes if the command is still executing. Use this command when the following conditions exist: o The remote host does not recognize Ctrl/O as the flush output character. o You want to terminate the output but not the execution of the process. DCL Format SEND AO UNIX Format send ao 3 Example % cd /bin % ls -l total 3464 -rwxr-xr-x 2 root 32768 Oct 19 1996 STTY -rwxr-xr-x 2 root 5120 Oct 19 1996 (characters not echoed) TELNET> SEND AO ^O % During a directory listing, the TELNET escape sequence (not echoed to the screen) returns to TELNET prompt. The SEND AO command aborts the UNIX ls command. 2 AYT SEND AYT (Are You There) reports if you are still connected to an established connection. DCL Format SEND AYT UNIX Format send ayt 3 Examples 1.$ TELNET> send ayt %TELNET-I-SESSION, Session 01, host d45lt, port 23 $ $:_TNA375: 13:53:18 (DCL) CPU=00:00:00.28 PF=448 IO=104 MEM=53 $ OpenVMS client to OpenVMS server. 2.% TELNET> send ayt %TELNET-I-SESSION, Session 01, host LUNA, port 23 % [YES] % OpenVMS client to UNIX server. 3.$ telnet> send ayt $:_TNA37: 13:50:20 (DCL) CPU=00:00:00.12 PF=331 IO=98 MEM=66 $ UNIX client to OpenVMS server. 4.% telnet> send ayt [Yes] % UNIX client to UNIX server. 2 BRK SEND BRK (Break) terminates execution of the last command you entered at the remote host. Use this command when the remote host does not recognize Ctrl/C as an interrupt character. DCL Format SEND BRK UNIX Format send brk 3 Example % cd /bin % ls -1 total 1464 -rwxr-xr-x 2 root 32768 Oct 19 1988 STTY -rwxr-xr-x 2 root 5120 Oct 19 1988 [ -rwxr-xr-x 1 root 45056 Oct 19 1988 adb lrwxr-xr-x 1 root 13 Aug 21 17:41 ar -> ../usr/bin/ar lrwxr-xr-x 1 root 13 Aug 21 17:41 as -> ../usr/bin/as (characters not echoed) TELNET> SEND BRK This example does the following: o Enters the UNIX ls command. o Enters the TELNET escape sequence. o Enters the TELNET SEND BRK command, which terminates execution of ls at the remote host. 2 EC SEND EC (Erase Character) deletes the last character you typed at the remote host. Use this command when the remote host does not recognize your Delete key. DCL Format SEND EC UNIX Format send ec 3 Example % mail (characters not echoed) TELNET> SEND EC Mail $Revision 4.2.4.2 $ Type ? for help. "/usr/spool/mail/debts": 1 message 1 new >N 1 debts Tue Sep 15 13:39 8/161 "Team Building" & This example: o Misspells the UNIX mail command. o Enters the TELNET escape sequence (not echoed to the screen) to return to the TELNET prompt. o Enters the TELNET SEND EC command, which deletes the last character typed (l) and returns to the remote host. 2 EL SEND EL (Erase Line) deletes the last line of text you entered on the remote host. Use this command when the remote host does not recognize your Delete key or command-line recall. DCL Format SEND EL UNIX Format send el 3 Example % mail (characters not echoed) TELNET> SEND EL % Mail Mail version 2.18 5/19/83. Type ? for help. "/usr/spool/mail/finder": 1 message 1 new >N 1 finder Tue Sep 15 13:39 8/161 "Getting Together" & This example: o Misspells the UNIX Mail command. o Enters the TELNET SEND EL command, which deletes the incorrect line mail and returns you to the remote host. o Enters the Mail command. 2 GA SEND GA (Go Ahead) signals the remote host that your local system is ready. Some applications require GA commands in either one or both directions. (Usually, Go Ahead is suppressed, so sending a GA has no effect.) DCL Format SEND GA UNIX Format send ga 2 IP SEND IP (Interrupt Program) interrupts the execution of the last command you entered on the remote host. The interrupt character clears the input and output paths to the remote host. The remote host interrupts the program that is processing. (This command has no effect in binary mode.) Use this command if either your terminal or the remote host does 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 can send data to the remote host and the remote host can receive the data. If you: o Get an %TELNET-E-INETERROR error message, there is a problem with the connection; the remote host is not able to receive data. 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 %TELNET-I-SESSION, Session 01, host nyx, port 23 No error message indicates the connection is active. (The information message also indicates the connection is active.) 2.% (characters not echoed) TELNET> SEND NOP %TELNET-S-REMCLOSED, Remote connection closed -TELNET-I-SESSION, Session 01, host nyx, port 23 TELNET> Indicates your connection has been broken. 2 SYNCH The SEND SYNCH command clears the communications path between your local system and the remote host. The SYNCH is sent in urgent mode (out-of-band, OOB). As a result, the following actions occur: 1. The local host immediately sends an interrupt character, placing it at the front of the data stream sent to the remote host. 2. The remote host immediately processes the interrupt character, ignoring any incoming data not yet processed, and then including a TELNET synchronization or interrupt character in the data stream it sends back to the local host. 3. The local host throws away all incoming data (rather than processing that data) until it detects the synchronization or interrupt character. This provides faster response time to the synchronization and interrupt characters. DCL Format SEND SYNCH UNIX Format send synch
