; FILE ULTRA144.SCR (MSMULTRA.SCR) ; ; An MS-DOS Kermit script program for dialing the Hayes ULTRA 144 modem, 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 38400, which is the highest support by this modem. ; ; Authors: Christine M.
