Hey Steve - I need to be very accurate in this and can not take the
chance of mis-interpreting your input...

I do find FRACK used in the 9612 TNC manual.  It makes sense.
I do not find frack used in the jnos 1.11 documentation under that name.

If you can, would you tell me exactly what timing parameters in jnos
implement the TNC FRACK timer function?
In addition, can you confirm that entering kiss mode locks out the TNC
frack timer so there is no timer-race?
