- ; An MS-DOS Kermit script program for dialing the US Robotics Sportster
- ; 14400 modem, to be used with MS-DOS Kermit 3.11 or later.
- ; The modem is set for V.32bis, compression, error correction, all types of
- ; fallback, RTS/CTS flow control, fixed interface speed of 57600 or 38400.
- ;
- ; To use: SET MODEM=SPORT (in DOS, before starting Kermit)
- ; or: DEFINE _MODEM SPORT (in Kermit, before dialing)
- ; and: Make sure Kermit executes the standard MSKERMIT.INI file.

- ; Modified 8 Aug 93 to fix typo (W1 is not a legal Sportster command).
