From a previous post:

Of course which protocol you use depends upon the "mode" of the IND$FILE 
transfer.  There are two protocols that come into play depending upon the 
status of the QUERY bit in the BIND parameters.  If it's set, then you must 
deal with DFT mode transfers (using structured fields).  If not set, then 
you work with CUT mode file transfers.  Any file transfer program you write 
should be able to handle either mode (unless you know specifically which one 
you'll be dealing with.)

BTW, I think the DFT mode protocol is also described in the PC3270 User's Guide
(or some such name) in Appendix C - File Transfer Data Streams.  This is the 
PC that IBM made somewhere around the time the XT came out.

Good Luck.
