;
; An MS-DOS Kermit script program for dialing the Zoom 14400 (V.32bis)
; modem, to be used with MS-DOS Kermit 3.11 or later. The modem is set
; up for compression, error correction, all types of fallback.
; RTS/CTS flow control, fixed interface speed of 57600 or 38400.
;
; Authors: Christine M. Gianone, Frank da Cruz; Columbia U, June 1993.
; PP14400.SCR adapted for Zoom modem by:
; Phillip Feldman <feldman@wiener.pstat.ucsb.edu>, Sept 1993.
; This script is almost identical to PP14400.SCR. Changes:
; a) Setting S46=2 does not work with Zoom modem. Must use S46=138.
; b) Default delay before execution of forced hangup is 20 seconds;
; S38=1 reduces this to 1 second.
;
; Revised April 1995 to account for RPI models.

set input timeout proceed ; Allow IF SUCCESS, IF FAILURE.

; Speed. Don't worry about modem, it autobauds up to 57600.
