; FILE TELEPCMC.SCR (MSTELEPC.SCR) ; ; An MS-DOS Kermit script program for dialing the MegaHertz XJack Telepath ; 14.4 PCMCIA Data/Fax Modem distributed by Gateway 2000, 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 57600, which is the highest supported by this modem. ; ; Authors: Christine M.
