3270, DSC, and SCS data streams intended for a 328X printer into data streams
that can be recognized by a printer attached to the AS/400
system.
400/REXX
See
REXX/400.
512-byte format
A format for
diskette 1 diskettes with 512 bytes per sector and 8 sectors per
track.

Any display
station, attached by twinaxial cable, that uses 5250 data
streams.
