[Simh] Interdata OS/32 question

I am using bash under the arm 64 version of debian mate on a pine64.  I am
remoting in using ssh. The remote system is bash under Linux mint.

After going through the guide to build a system from tapes there is a
section that enables more terminals, disks and probably other things.  All
is well until this point.  After the system and install the system gets
rebooted into the new configuration.

It is at that time when things go sideways.

All the text printed by OS/32 now has control characters with it and it
doesn't seem to understand input any more.  If you do a set time command
and hit enter the cursor returns to the beginning of the line but I can't
tell if the prompt appears again due to the control characters at the
beginning of the line.

I don't know how to record a session or I would provide a log.
