The trace display would look like this:

The
byte
column shows the offset into the packet of the beginning byte of the line.
The
hex display
column shows the next 16 bytes of the packet, exactly as
received, in standard hex format. The
shifted ASCII
column attempts to decode
the high order seven bits of each byte as an ASCII character code. The
ASCII
column
attempts to decode the low order seven bits of each byte as an ASCII
character code. In a standard AX.25 packet, the callsign address field will be
displayed correctly in the shifted ASCII column. A text message will be displayed
correctly in the ASCII column. Non-printing characters and control characters are
displayed in both ASCII fields as ".". You can examine the hex display field to
see the contents of the sub-station ID byte and the control bytes used by the
protocol. Protocol details are discussed in Chapter 9.
