* Chat -- a program for automatic session establishment (i.e. dial
* the phone and log in).
*
+ * Standard termination codes:
+ * 0 - successful completion of the script
+ * 1 - invalid argument, expect string too large, etc.
+ * 2 - error on an I/O operation or fatal error condtion.
+ * 3 - timeout waiting for a simple string.
+ * 4 - the first string declared as "ABORT"
+ * 5 - the second string declared as "ABORT"
+ * 6 - ... and so on for successive ABORT strings.
+ *
* This software is in the public domain.
*
* Please send all bug reports, requests for information, etc. to:
* Al Longyear (longyear@netcom.com)
* (I was the last person to change this code.)
*
+ * Added -r "report file" switch & REPORT keyword.
+ * Robert Geer <bgeer@xmission.com>
