.COMMENT \ *** SMODEM3 *** CP/M SMARTMODEM PROGRAMME ========================= Version 3.6 by Walter Blady THIS PROGRAMME WAS ORIGINALLY MODEM7.MAC WRITTEN BY WARD CHRISTENSEN AND REVISED BY M.ZEIGER AND J.MILLS FOR THE PMMI MODEM BOARD. FULL CREDITS FOR EXPERIENCE AND TALENT THAT MADE THIS PROGRAMME POSSIBLE, BELONG SOLELY TO THESE PEOPLE. MANY ADDITIONAL ROUTINES INCLUDED ARE COPYRIGHTED (1980) BY MARK M.ZEIGER AND J.MILLS. PERMISSION IS GRANTED TO USE BUT NOT SELL THESE ROUTINES. THIS VERSION WAS PREPARED BY WALTER BLADY FOR USE WITH THE HAYES SMARTMODEM USING RS232 I/O ON THE DISC JOCKEY CONTROLLER BOARD. AN EXTENDED AND MORE FLEXIBLE AUTO-DIAL FEATURE WAS ADDED. THE USER NOW HAS THE ABILITY TO KEEP SEVERAL TELEPHONE DIRECTORIES ON THE DISK AND THESE MAY BE EDDITED WHEN NEW INFORMATION MUST BE ADDED. THE ORIGIONAL SOURCE CODE WAS PREPARED FOR THE MAC ASSEMBLER. THIS VERSION HAS BEEN ADAPTED FOR COMPILATION WITH MICROSOFT'S M80 ASSEMBLER.

The use of this scheme will guarantee detection of all single and double bit errors, all errors with an odd number of error bits, all burst errors of length 16 or less, 99.9969% of all 17-bit error bursts, and 99.9984% of all possible longer error bursts.
