CP/M SMARTMODEM PROGRAM
=======================
Version 3.6
Adapted by Walter Blady
Upgraded to version 3.7 by Jim Mills, CACHE.
Configured for: KAYPRO II
KAYPRO II Configuration by
Micro Cornucopia
PO BOX 223
Bend OR 97709
To assemble this program and create a CP/M 'COM' file, use
MICROSOFT'S M80 assembler and the following commands:
M80 =SMODEMK
L80 /P:100,SMODEMK,SMODEMK/N/E
FOR FULL INFORMATION ON THE USE OF 'SMODEM', PLEASE REFER TO
THE FILE 'SMODEM.DOC'.
THIS PROGRAM 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 PROGRAM 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. 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
EDITED WHEN NEW INFORMATION MUST BE ADDED.
02/13/82: Fixed program to allow "A" and "O" options to be
specified by user. Previously, you had to use direct cmnds
to SMARTMODEM or use the dialer routine to connect!
Jim Mills, CACHE.

CRCSUBS (Cyclic Redundancy Code Subroutines) version 1.20
These subroutines will compute and check a true 16-bit
Cyclic Redundancy Code for a message of arbitrary length.
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. (Ref: Computer Networks,
