Daniel, thanks for your reply. I had thought I attempted it that way, but apparently had something wrong. I used content type “application/edi-x12”, pub.string:stringToBytes, pub.io:bytesToStream and it worked. I also stripped some carraige return characters from the string beforehand, not sure if they were causing a problem, but they weren’t supposed to be there anyway.
