I-Data 5250 ALLY - Manual (Page 224)

AGILE 5250 ALLY User’s Guide and Reference Page B-42
Command: Transparent (TRN)
Format: 35 nn [data]
Printers: 4214, 5224, 5225
Action: Causes the printer to enter a transparent printer mode,
where the subsequent nn characters are not checked for
control codes.
This command allows printing of the bit images
previously associated with control characters by the Load
Alternate Characters (LAC) command.
The count parameter, nn, unlike the count parameter for
format commands, does not include the count byte itself.
The count parameter is the count of following bytes not
to be checked for SCS/DCA control codes.
IBMEMUL: The 5250 ALLY allows data to be sent directly to the
printer (or other output device) with this command.
After receiving the Transparent command, it sends the
following nn bytes directly out the output port.
Unlike the ASCII Transparent (ATRN) mode,
Transparent data is translated before it is sent to the
target printer.

Command: Numeric Backspace (NBS)
Format: 36
Printers: 5219
Action: This command is the same as Back Space (BS).
