; MS-DOS Kermit script program for dialing Practical Peripherals from V.22bis
; to V.34, that have error correction and compression. To be used with MS-DOS
; Kermit 3.12 or later. The modem is set up for compression, error
; correction, all types of fallback. RTS/CTS flow control, fixed interface
; speed of 115200, 57600, 38400, or 9600 bps depending on the modem model.
;
; Authors: Christine M. Gianone, Frank da Cruz; Columbia U, June 1993
; Revised: December 1993 to accommodate the 9600bps models;
; Acknowledgements to David Zakai of SUNY-Health Science Center
; at Brooklyn for info about them and debugging help.
; Revised: June 1995 for V.22bis and V.FC models.
