Thank you, Richard, you are absolutely right. Looking back at the documentation for the instrument, I found the following: "The data format complies with JIS 7Bits-transmission code with a baud rate of 19230. " I had overlooked the JIS transmission code because I didn't know what that meant. (It is the Japanese Industrial Standard). Changing my script to display the data one character at a time, I found it was sprinkled with escape characters that Japanese machines use to switch from ASCII to Kanji characters and back. Does Python have a module that will translate the data stream and display normal ASCII characters? The escape codes appear to alter the values of the characters in some systematic way. Thanks again for your help. -- http://mail.python.org/mailman/listinfo/python-list
