Realport config w/ signature device

I’m having problems getting realport to work with devices that produce binary data, ie ascii 255.
rtty works fine, but I would rather use Realport.
Any suggestions?

Product/firmware ver/driver ver/OS? Make sure these are all up to date.

If being on the latest and greatest doesn’t resolve the problem, best bet would be to call into Technical Support so a deeper look at your configuration and issue can be taken. I don’t know of anything offhand that would cause this behavior.
