I remember such a problem could occur if you have enabled your
terminal profile on this DTC port to do Native Language IO,
i.e. NLIO = Y. You can check/disable that in NMMGR.

You might want to ask your Response Center if that problem
has been fixed with a recent patch, if it is indeed this
problem you are having; if not it will be best to produce
a memory dump for the RC to analyze the problem.
