Do you have a user manual for your TNC? I only have the KPC-3 manual

Slottime sets how long the TNC should wait before checking to see if
it should try to gain access to the channel.

Persist controls the "odds" of whether the channel should be checked or not.
These two combined determine when to try sending a packet. The unit
waits the desired slottime, then the unit picks a random number
between 0 and 255. If that random number is less than persist, the
radio keys up, otherwise it goes back to the top waiting for slottime
to expire. With persist set at 0, it's pretty hard to get a random
number less than zero.

Dwait is the other way to hold off... check that manual.
