Sending to Mazak 640

We are using an offline DNC system to send files to the Mazak 640M Controller and the part programs is received at the CNC.

The odd thing, we get the part program there in tack but all the comments are modified.

The comment line is there in English but then also translated to portuguese)
(DATE 06/14/14 DATA 06/14/14)

All the G code is fine and if there are any English words in comments they all get translated to show the portuguese as well). Very odd, but I suspect this is a setting on the CNC controller when loading via RS232.

Since the G code get there, and we can send in programs, the baud rate, data bits and stop don't matter to us. Sending files with NO comments gets there fine.

Any ideas??? Thank you in advance!
