Re: debugging KISS basics

[Pidoux <f6bvp@free.fr>]

Chris,

When TNC is in KISS mode you cannot issue any more command to it.
Every data received are transparently transmitted (except the escape sequence for putting it back into TERMinal mode.)
Thus, you must set the TNC parameters (like the serial port speed, MYCALL, dual port mode if TNC3, and adjust different 
audio TX levels for once) before putting the TNC in kiss mode.
In addition, once AX25 driver is loaded, you cannot converse with TNC using your favorite Linux terminal communication 
program.
My option is to boot Linux system without AX25 drivers, configure TNC parameters, verify that you can listen to AX25 
traffic and connect to a local AX25 station using 1200 or 9600 baud port. Then, when you estimate your TNC is doing 
well, send it the escape sequence command to turn it into KISS mode.
You can leave it in KISS mode forever.
After that you are ready to load AX25 and mkiss drivers and run AX25 applications.
Listen utility will help you verify the TNC can pass through AX25 traffic.
