Guardian was interesting.  The normal connection (from my point of
view, anyway) was via a TATM (Tandem Asynchronous Terminal
Multiplexer), which buffered the characters, but it didn't interrupt
the processor until one of 4 configurable characters were entered
(typically CR, abort, end of input).  This didn't offer line editing,
and the workarounds were painful.

There was also a block mode, mainly for end user applications, though
the “full screen” editor also used it.
