Sounds like an oversight. Creating a null method would be fine.
The proper fix is probably to change the class definition so that
a serial-stream inherits the output-stream method for stream-force-ouput
which does nothing:
(defclass serial-stream (driver input-stream output-stream)
((serial-unread-char :initform nil))
(:default-initargs :driver-buffer-size 4))
I say "probably" because I haven't tested this.
