    Hello everybody,

    I am wondering whether there is a "nice" way to enable/ disable KISS mode on
    a TNC-2 with Linux.
    (I am using an MFJ 1270C, but I think the same is for all the TNC-2 type
    TNCs...)

    In various HOWTO, it is written that you can do it with the minicom.
    Yes, this is true but I do not like it at all.

    I have tried to send to my /dev/tnc ( which is a soft link to /dev/ttyS1 in
    my case) the commands KISS ON and RESTART but no luck.
    The method I used to do it was:

    TO ENABLE
    1. setserial /dev/ttyS1 baud_base 9600 (because my TNC has as serial port
    speed 9600, so I must change the default speed of PC serial port)
    2. echo "KISS ON" > /dev/tnc
    3. echo "RESTART" > /dev/tnc
    So, I did not see any STA and CON led flashing. (and the TNC was not in KISS
    mode)

    The only working method for me is to start minicom and issue the above
    commands. (KISS ON and RESTART).
    (But even in this case the leds are not flashing, though KISS mode is
    actually enabled...???...Strange...)

    TO DISABLE
    I did not manage to disable KISS mode with Linux at all!!!
    The method I follow to disale KISS mode is, to reboot in DOS, start JNOS
    program (which it is already configured in KISS) and exit JNOS in the
    end.....!!!!! This works. When I start JNOS, the CON and STA leds are
    flashing and also during the exit from JNOS, again the CON and STA led are
    flashing. Everything works fine in JNOS case.

    According to the manual of MFJ, it says the way to enable and disable KISS
    mode if you are using the JNOS program (Enable: KISS ON and RESTART and
    Disable: param <interface_name> 255 from the command prompt of JNOS).
    It does not mention anything about other software or operating system.
    Also, there is another method, according to MFJ manual, in order to disable
    KISS mode. To remove jumper JMP5, and wait 5 few minutes, then reinstall
    it.......!!!!!!!!

    Does anyone knows and nice way, like the one in JNOS?

    Thanks.
