This package contains an implementation of the KISS host to TNC protocol
for the TAPR TNC-1 and clones, including the Heath HD-4040. It was originally
written by Marc Kaufman WB6ECE, kaufman@shasta.stanford.edu, with several bugs
corrected by Gerard VanderGrinten, PA0GRI.
The files TNC1BOOT.* are TNCBUG, a mikbug type debugging and bootloader for
the TNC-1. Note that ALL interrupts are available to the RAM program, via
an interrupt re-vector area in low RAM.
The files TNC1CAL.* are CALIB, a simple tone calibration program for the
TNC. It provides a very convenient way to adjust the modem.
The files TNC1KISS.* are the actual KISS implementation. As provided, the
program is set up to execute from ROM, starting at address F800. It has
only been tested while residing in the top 2k of an 8k 2764 EPROM, but it
should be possible to put the .MOT or .HEX file into a 2716 and make it work.
The file TNC1PARM.DOC documents the bytes beginning at F800, which contain
constants defining the default settings of several TNC parameters.
The NOVRAM is not used at all.
