Its been so long since I learned some of them that I don't recall where.
They would have been described in the definitions of the total packet
format which may be on line these days. Probably at tapr.org.

UI is beacon or disconnected data transmission.
C is connect request
Rn is Roger packet number (n goes from 1 to 7).
I forget what reject is.
Sn is sending packets ending in packet n.
I suppose D is disconnect.

There might be something in the owner's or operator's manual for your
TNC different TNC codes display them differently.
