I can answer one of your questions:

Yes. The TNC is put into "KISS" ('Keep It Simple St...') mode, and becomes
a dumb bitmodem, in affect. The kernel then handles everything. The gives
you much more control, of course - otherwise you could not have your PC
directing (and driected by) ax25.
Alternately, you could use a TNC and its inbuilt ax.25 plus PBBS, and no
PC at all except to read messages people leave you. But then you'd miss
out on all this fun. ;)
