    If OS-9 can send, then that part of the pak is fine. If some of the
RSDOS terminal programs do not, perhaps they initialize the pak
differently as they are expecting to talk to a real modem. The OS-9
drivers are initializing the pak to talk to a terminal.

    I would try shorting all (both?) of the status outputs to all the
status inputs. That may fool everyone involved. You could even try full
loopback mode (tx to rx). The pak should return all bytes sent to it.
