It turns out that not only is the ttl code not recognized by the receiving computer from the file that I wrote but it will also not be recognized from the sendTTL sample file included in DirectRT. However, the receiving computer will recognize and encode a ttl code if it is send from the I/O test. Thus, this seems to be a DirectRT problem. Any advice would be greatly appreciated as it is critical that I am able to send ttl codes.

Thanks,
Scott
