/* Note well:
* In the IBM "3270 Information Display System: Data Stream Programmer's Reference"
* document, the references to bit numbers in the text and tables
* are based upon the "MSB 0" bit numbering scheme.
* That is: bits are numbered in a byte from left-to-right:
* "Bit 0" is the MSB of the byte
* "Bit 7" is the LSB of the byte
*/
/*
ToDo:
- better tree display: e.g., separate tree for each order code ....
- review 'structured field grouping: 5.2
- Telnet uses 0xFF as IAC ["interpret as command"] and thus for
telnet: any actual 0xFF bytes in a 3270 data stream will be prefixed with
a 0xFF escape. The escapes should be removed from the TVB before the
buffer is passed to this dissector. See packet-telnet.c
- Show the 'as a fraction" display as xx/yy ?
