; File SUPRV32B.SCR -- minor modification of Christine's HAYES.SCR.
; To be used with MS-DOS Kermit 3.11 or later.
;
; Stored in Kermit Distribution as MSMSUPRA.SCR; rename to SUPRA SCR
; if necessary so the DIAL macro can find it.  Place this file in your
; current directory or in any directory in your DOS PATH, and then set the
; DOS environment variable, MODEM, to be SUPRA.  Give the following command
; at the DOS prompt before starting Kermit, or add it to your AUTOEXEC.BAT
; file:
;
;   SET MODEM=SUPRA
;
; An MS-DOS Kermit script program for dialing a SupraFAXmodem V.32bis
; modem and compatibles.  Will probably work with the non-fax and V.32
; versions of this modem, but this has not been tested.  The Supra, 
; like most V.32/V.32bis modems, is Hayes-compatible up to the point
; that one starts dealing with buffering, error-correction, and
; compression modes.
;
; The modem setup specified below provides for "error correction call
; progress" reporting.  This may be useful in making other session decisions,
; e.g., max packet sizes/windows, and should be displayed to the user.
; Also, modem is set up for RTS/CTS, buffering, local flow control, etc. and
; Kermit is placed into the corresponding modes.  One should not attempt to
; use one of these things without an adequate shielded cable.  See also the
; speed discussion below.
;
; Lines containing *** may require local editing.
; Expects variable %\1 to contain the phone number; this is done
; by the DIAL macro defined in MSKERMIT.INI.
;
; Uses ATD (modem's default dialing method) to dial the number.
; Force tone dialing by including T as first character of phone
; number, or pulse dialing by including P as first character.
;
; Sets SUCCESS flag if dialing succeeds, sets FAILURE flag 
; if it fails.
;
;  Author: John C. Klensin, August 1992 (modified from HAYES.SCR by
;     Christine M. Gianone (July 1991).  Requires MS-DOS Kermit 3.11 or later.
;
; The normal DTE <-> DCE speed of this modem is 57.6 Kbps, regardless of the
; line or character speed.  Set that number here, regardless of what the
; DIALUPS file says.  However, this may exceed the speed at which may MSDOS
; computers can deal with characters and should be reduced if necessary.
