| 2 | * Chat -- a program for automatic session establishment (i.e. dial |
| 3 | * the phone and log in). |
| 4 | * |
| 5 | * Standard termination codes: |
| 6 | * 0 - successful completion of the script |
| 7 | * 1 - invalid argument, expect string too large, etc. |
| 8 | * 2 - error on an I/O operation or fatal error condition. |
| 9 | * 3 - timeout waiting for a simple string. |
| 10 | * 4 - the first string declared as "ABORT" |
| 11 | * 5 - the second string declared as "ABORT" |
| 12 | * 6 - ... and so on for successive ABORT strings. |
| 13 | * |
| 14 | * This software is in the public domain. |
| 15 | * |
| 16 | * ----------------- |
lh | 9ed821d | 2023-04-07 01:36:19 -0700 | [diff] [blame] | 17 | * 22-May-99 added environment substitutuion, enabled with -E switch. |
| 18 | * Andreas Arens <andras@cityweb.de>. |
| 19 | * |
| 20 | * 12-May-99 added a feature to read data to be sent from a file, |
| 21 | * if the send string starts with @. Idea from gpk <gpk@onramp.net>. |
| 22 | * |
| 23 | * added -T and -U option and \T and \U substitution to pass a phone |
| 24 | * number into chat script. Two are needed for some ISDN TA applications. |
| 25 | * Keith Dart <kdart@cisco.com> |
| 26 | * |
| 27 | * |
| 28 | * Added SAY keyword to send output to stderr. |
| 29 | * This allows to turn ECHO OFF and to output specific, user selected, |
| 30 | * text to give progress messages. This best works when stderr |
| 31 | * exists (i.e.: pppd in nodetach mode). |
| 32 | * |
| 33 | * Added HANGUP directives to allow for us to be called |
| 34 | * back. When HANGUP is set to NO, chat will not hangup at HUP signal. |
| 35 | * We rely on timeouts in that case. |
| 36 | * |
| 37 | * Added CLR_ABORT to clear previously set ABORT string. This has been |
| 38 | * dictated by the HANGUP above as "NO CARRIER" (for example) must be |
| 39 | * an ABORT condition until we know the other host is going to close |
| 40 | * the connection for call back. As soon as we have completed the |
| 41 | * first stage of the call back sequence, "NO CARRIER" is a valid, non |
| 42 | * fatal string. As soon as we got called back (probably get "CONNECT"), |
| 43 | * we should re-arm the ABORT "NO CARRIER". Hence the CLR_ABORT command. |
| 44 | * Note that CLR_ABORT packs the abort_strings[] array so that we do not |
| 45 | * have unused entries not being reclaimed. |
| 46 | * |
| 47 | * In the same vein as above, added CLR_REPORT keyword. |
| 48 | * |
| 49 | * Allow for comments. Line starting with '#' are comments and are |
| 50 | * ignored. If a '#' is to be expected as the first character, the |
| 51 | * expect string must be quoted. |

| 54 | * Francis Demierre <Francis@SwissMail.Com> |
| 55 | * Thu May 15 17:15:40 MET DST 1997 |
| 56 | * |
| 57 | * |
| 58 | * Added -r "report file" switch & REPORT keyword. |
| 59 | * Robert Geer <bgeer@xmission.com> |
| 60 | * |
| 61 | * Added -s "use stderr" and -S "don't use syslog" switches. |
