; FILE SPORT.SCR (MSMSPORT.SCR)
;
; An MS-DOS Kermit script program for dialing the US Robotics Sportster or
; Courier 14400 or 28800 modem, to be used with MS-DOS Kermit 3.12 or later.
; The modem is set for RTS/CTS flow control, fixed interface speed of 57600,
; and to negotiate highest modulation, compression, with error correction
; with all types of fallback.
;
; To use: SET MODEM=SPORT (in DOS, before starting Kermit)
; or: DEFINE _MODEM SPORT (in Kermit, before dialing)
; or: SET MODEM SPORT (in Kermit, v3.14 or later)
; and: Make sure Kermit executes the standard MSKERMIT.INI file.
;
; Authors: Christine M. Gianone, Frank da Cruz; Columbia U, June 1993
; Modified 8 Aug 93 to fix typo (W1 is not a legal Sportster command).
; 10 Nov 93 - eliminate DSR check.
; 18 Jan 95 - update for version 3.14, SET CARRIER, etc.
; 24 Mar 95 - update comments after testing with V.34 model.
