    I don't think this was among the problems i experienced during the RTTY test.  However, I di leave the radio for a nap and all was woking fine.  Three hours later when i returned no DAX audio was evident.  I rebooted SSDR and N1MM+ and all worked without any fuss.  I suspect a Windows power management issue.

    Were you using the latest version of N1MM?  They fixed several bugs in their com handling logic

    Jim, I ran all weekend with a similar configuration -- CAT to N1MM Logger+ (latest version as of 9/20), MMTTY and 2Tone.  I had no issues and I know several others without issues also.  Looking at what you have on the screen, it looks like there is CAT data going to output window in MMTTY.  Have you gone through the setup in the N1MM Logger+ docs to ensure you have the settings right?  The docs can be found here.  I'll look over them and see if I can find what might be wrong.  http://n1mm.hamdocs.com/tiki-index.php?page=Digital+-+MMTTY+for+RTTY+Support

    It sure looks like two clients are trying to use COM5. One is obviously N1MM+. I'm real surprised to see CAT commands showing up in the RTTY terminal. Are your settings set for FSK or AFSK? I guess the trick is to find out what else is competing for COM5. A setting in MMTTY or 2Tone? Another application? Should be easy enough to isolate it.
