Serial pots were used for things other than terminals... Many printers
had serial interfaces, as did the TU58 (which is what started this
discussion).

While timesharing was rare on machines without memory managemnt, it was
not uncommon to have 3 or 4 serial ports in such machines.

Be warned that the DL11 (simple serial port) and the DZ11 (etc --
'multiplexer' serial ports) look very different in software! Older OSes
may well only support the former.
