* 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.
