Idea from gpk <gpk@onramp.net>. - * - * added -T and -U option and \T and \U substitution to pass a phone - * number into chat script. Two are needed for some ISDN TA applications. - * Keith Dart <kdart@cisco.com> - * - * - * Added SAY keyword to send output to stderr. - * This allows to turn ECHO OFF and to output specific, user selected, - * text to give progress messages. This best works when stderr - * exists (i.e.: pppd in nodetach mode). - * - * Added HANGUP directives to allow for us to be called - * back. When HANGUP is set to NO, chat will not hangup at HUP signal. - * We rely on timeouts in that case. - * - * Added CLR_ABORT to clear previously set ABORT string. This has been - * dictated by the HANGUP above as "NO CARRIER" (for example) must be - * an ABORT condition until we know the other host is going to close - * the connection for call back. As soon as we have completed the - * first stage of the call back sequence, "NO CARRIER" is a valid, non - * fatal string. As soon as we got called back (probably get "CONNECT"), - * we should re-arm the ABORT "NO CARRIER". Hence the CLR_ABORT command. - * Note that CLR_ABORT packs the abort_strings[] array so that we do not - * have unused entries not being reclaimed. - * - * In the same vein as above, added CLR_REPORT keyword. - * - * Allow for comments. Line starting with '#' are comments and are - * ignored. If a '#' is to be expected as the first character, the - * expect string must be quoted. - * - * - * Francis Demierre <Francis@SwissMail.Com> - * Thu May 15 17:15:40 MET DST 1997 - * - * - * Added -r "report file" switch & REPORT keyword. - * Robert Geer <bgeer@xmission.com> - * - * Added -s "use stderr" and -S "don't use syslog" switches. - * June 18, 1997 - * Karl O.
