Code V Emulation for Printing

We are currently doing a lot of work to migrate our Twinax printers to
Ethernet.  I have several Decision Data 6704's that are really
Printronix under the hood.  Our programs are addressing these in their
proprietary Code V language to print labels.  I am sending the same
spool files that work fine on the 6704 to an IBM 6400 with the Code V
emulation option, and the graphics start mode character changed to what
I believe we are using, which is 5F.  To get this value, I copied the
spool file to a database file and did a display Hex in PDM.  

The printer is set up as a remote writer with an IP address.  It is
printing, but the print codes are just printing as text, it is evidently
ignoring the codes entirely.  Host Print Transform is *YES in the remote
writer definition, and I have tried various models.  I know this is a
pretty special case, and therefore a long shot, but anyone ever tried
this that can suggest something?  

Thanks,
