Add an "int ser" parameter here.

Here, check that ser is between 0 and (255-64), and add ser to 64.

Here, pass synth->ser to spk_ttyio_initialise_ldisc()


That way, people want easily configure the serial port with the existing

and AIUI we should be getting the same support as before, and thus get
this tested and pushed upstream.
