Realport config w/ signature device

I’m losing data using realport with devices that produce binary data. ie ascii 255
I’m using ts8s and ts16s on AIX 5.2.
rtty works fine, but I’d rather use Realport
any suggestions?

Recommend comparing port parameters between the RTTY (pseudo) port and the RealPort port.

If the port settings are identical, I recommend contacting Technical Support to pursue this further.
