For those who don't seem to be able to find it, here is the
portion of the specification which treats KISS ACK.
KISS with this capability is built in to the Kantronics TNCS,
and EPROM images are available for TNC2 clones.
Acknowledgement Mode
The G8BPQ Acknowledgement Mode is intended mainly for HF
operation where data that has been sent to the TNC for
transmission may not actually be transmitted for an extended
period of time.
When this mode is selected, the master unit would send the
special $xC command byte, causing the selected TNC to return an
acknowledgement when the frame has been sent. This allows the
master to start his timing parameters (FRACK, etc.) at the time
the frame actually left the TNC. For instance, if the master
wants to send a data frame to TNC with address 5 and wants to use
the Acknowledgement Mode, the frame would begin with:
$C0 $5C $aa $bb data to be transmitted $C0
The $aa and $bb in this example are not transmitted, but are
returned to the master by the TNC when the frame is transmitted.
This allows you to sequentially number the frames if you desire,
as these two bytes may be any value. When the TNC has transmitted
this frame it will send the following back to the master:
$C0 $5C $aa $bb $C0
