I looked into the problem, and I think I know what is causing it.
Unfortunately, there isn't much I can do about it.  I am reasonably certain
that DEC has been bit by their own bug.  The system service to sense terminal
characteristics is supposed to return stuff you can send to the set
characteristics service; it doesn't.  All the information is there, but
it takes a page of code to rearrange it properly.  I begin to suspect that
DEC isn't aware of this.

	The program seems to continue to function after the error, so
I suggest that you ignore it until they fix it.  I will let them know about it.
