Righto. SS.Opt (which tmode does) only works on the Path Descriptor, which is
originally is set when created, from the Device Descriptor module.

You can imagine why this is... example: your terminal program uses SS.Opt to
turn off echo. You sure don't want this to be permanent and affect following
programs which might use the same window descriptor later. Same with disks etc.

A device descriptor describes the default settings and/or maximum capabilities
(like with DS80 drives) of a device. Path descriptors are concerned with
currently opened paths/files specific to processes.
