KISS Mode
9.3.1
KISS Mode Description
KISS mode is also a “framed” data mode, similar to HOST. However, when in KISS
mode the TALON becomes just a packet assembler/disassembler (PAD).
In the KISS Mode, the TALON simply passes all received data to the computer in a KISS
frame, and the computer program is responsible for all processing of that data, including
decisions concerning routing, Digipeating, and other control decisions. To transmit data,
again, the program is responsible for processing data to send in a packet and enclosing
that data in a KISS frame to be sent to the TALON. (References for KISS mode are at
end of this section)
A computer program can send any type of data (such as TCP/IP, or any other protocol)
enclosed in AX.25 packets, and sent to the TALON in KISS frames.
Very few of the TALON’s commands (and none of its other functions), are available
when it is in KISS mode. The operating functions that are available depend solely on the
computer program used.
The TALON converts the packets of synchronous data being received from the radio link
into packets of asynchronous data to be passed to the computer over the serial port, and
converts the packets of asynchronous data from the computer into the synchronous
format suitable for radio transmission. The TALON retains the responsibility of
determining proper timing for channel access.
To place the TALON in KISS Mode, at the command prompt (cmd:), type INTFACE
KISS and ENTER. Then, send a RESET command, or cycle power (off/on) to the
TALON.
The TALON will remain in KISS interface mode, until it receives the KISS exit code, or
it has been hard reset.
9.3.2
Exiting KISS mode
The TCP/IP program should include the command to EXIT KISS mode in the TALON.
See that programs documentation for the proper command.
To enter the EXIT KISS command manually (from a regular terminal program), send a
three character sequence which includes a FEND (frame-end) character (ASCII code 192
or Hexadecimal 0xC0), FF (ASCII code 255), then another FEND character. A FEND
character can be entered manually, by pressing and holding the ALT key, entering 192
from the number key pad on the right side of the keyboard, and then releasing the ALT
key. The ASCII code 255 can be entered by pressing and holding the ALT key, entering
