;
; An MS-DOS Kermit script program for dialing the ZyXEL 1496
; 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.
; Further modified for ZyXEL modem by:
; Richard Stanton <stanton@haas.berkeley.edu>
;
; This script is almost identical to ZOOM.SCR. Changes:
;
; W1 means nothing to ZyXEL.
; S95 register doesn't exist.
; X5 gives more information than X4.
; &N0 tells modem to negotiate highest rate possible.
; &H3 gives RTS/CTS flow control, rather than &K3.
; &Y1 tells modem to send nondestructive, expedited breaks.
; &K4 tells modem to try V42/V42bis, then work down (through MNP etc.)
; No forced hangup settings.
