67c478bd9Sstevel@tonic-gate * Chat -- a program for automatic session establishment (i.e. dial
77c478bd9Sstevel@tonic-gate * the phone and log in).
87c478bd9Sstevel@tonic-gate *
97c478bd9Sstevel@tonic-gate * Standard termination codes:
107c478bd9Sstevel@tonic-gate * 0 - successful completion of the script
117c478bd9Sstevel@tonic-gate * 1 - invalid argument, expect string too large, etc.
127c478bd9Sstevel@tonic-gate * 2 - error on an I/O operation or fatal error condition.
137c478bd9Sstevel@tonic-gate * 3 - timeout waiting for a simple string.
147c478bd9Sstevel@tonic-gate * 4 - the first string declared as "ABORT"
157c478bd9Sstevel@tonic-gate * 5 - the second string declared as "ABORT"
167c478bd9Sstevel@tonic-gate * 6 - ... and so on for successive ABORT strings.

207c478bd9Sstevel@tonic-gate * -----------------
217c478bd9Sstevel@tonic-gate * 22-May-99 added environment substitutuion, enabled with -E switch.
227c478bd9Sstevel@tonic-gate * Andreas Arens <andras@cityweb.de>.
237c478bd9Sstevel@tonic-gate *
247c478bd9Sstevel@tonic-gate * 12-May-99 added a feature to read data to be sent from a file,
257c478bd9Sstevel@tonic-gate * if the send string starts with @. Idea from gpk <gpk@onramp.net>.
267c478bd9Sstevel@tonic-gate *
277c478bd9Sstevel@tonic-gate * added -T and -U option and \T and \U substitution to pass a phone
287c478bd9Sstevel@tonic-gate * number into chat script. Two are needed for some ISDN TA applications.
297c478bd9Sstevel@tonic-gate * Keith Dart <kdart@cisco.com>
307c478bd9Sstevel@tonic-gate *
317c478bd9Sstevel@tonic-gate *
327c478bd9Sstevel@tonic-gate * Added SAY keyword to send output to stderr.
337c478bd9Sstevel@tonic-gate * This allows to turn ECHO OFF and to output specific, user selected,
347c478bd9Sstevel@tonic-gate * text to give progress messages. This best works when stderr
357c478bd9Sstevel@tonic-gate * exists (i.e.: pppd in nodetach mode).
367c478bd9Sstevel@tonic-gate *
377c478bd9Sstevel@tonic-gate * Added HANGUP directives to allow for us to be called
387c478bd9Sstevel@tonic-gate * back. When HANGUP is set to NO, chat will not hangup at HUP signal.
397c478bd9Sstevel@tonic-gate * We rely on timeouts in that case.
407c478bd9Sstevel@tonic-gate *
417c478bd9Sstevel@tonic-gate * Added CLR_ABORT to clear previously set ABORT string. This has been
427c478bd9Sstevel@tonic-gate * dictated by the HANGUP above as "NO CARRIER" (for example) must be
437c478bd9Sstevel@tonic-gate * an ABORT condition until we know the other host is going to close
447c478bd9Sstevel@tonic-gate * the connection for call back. As soon as we have completed the
457c478bd9Sstevel@tonic-gate * first stage of the call back sequence, "NO CARRIER" is a valid, non
467c478bd9Sstevel@tonic-gate * fatal string. As soon as we got called back (probably get "CONNECT"),
477c478bd9Sstevel@tonic-gate * we should re-arm the ABORT "NO CARRIER". Hence the CLR_ABORT command.
487c478bd9Sstevel@tonic-gate * Note that CLR_ABORT packs the abort_strings[] array so that we do not
497c478bd9Sstevel@tonic-gate * have unused entries not being reclaimed.
507c478bd9Sstevel@tonic-gate *
517c478bd9Sstevel@tonic-gate * In the same vein as above, added CLR_REPORT keyword.
527c478bd9Sstevel@tonic-gate *
537c478bd9Sstevel@tonic-gate * Allow for comments. Line starting with '#' are comments and are
547c478bd9Sstevel@tonic-gate * ignored. If a '#' is to be expected as the first character, the
557c478bd9Sstevel@tonic-gate * expect string must be quoted.

607c478bd9Sstevel@tonic-gate *
617c478bd9Sstevel@tonic-gate *
627c478bd9Sstevel@tonic-gate * Added -r "report file" switch & REPORT keyword.
637c478bd9Sstevel@tonic-gate * Robert Geer <bgeer@xmission.com>
647c478bd9Sstevel@tonic-gate *
657c478bd9Sstevel@tonic-gate * Added -s "use stderr" and -S "don't use syslog" switches.
