61 ToDo:
62 - better tree display: e.g., separate tree for each order code ....
63 - review 'structured field grouping: 5.2
64 - Telnet uses 0xFF as IAC ["interpret as command"] and thus for
65 telnet: any actual 0xFF bytes in a 3270 data stream will be prefixed with
66 a 0xFF escape. The escapes should be removed from the TVB before the
67 buffer is passed to this dissector. See packet-telnet.c
68 - Show the 'as a fraction" display as xx/yy ?
