Writelog MMTTY and 2Tone Issue

Anybody using Writelog for the Round Up this weekend?  I would like some assistance in getting my 6400 to send messages using 2Tone or MMTTY.  I can transmit fine in MMTTY and sends macros successfully.  However, when I configure RTTYrite, I can get it to key, but all I get is a diddle idle and I can see the message scroll, but it isn't sending. I can provide more detail in what settings I have tried.  Thanks in advance!
