I'm not convinced the serial port is viable on my machine. I get the

when I hook up the other side via a null modem, the status doesn't
change (at all) the way other SSC machines do. So, lots of tweaks to
the configuration registers later, I still don't have anything coming
out the wire.
Could it possibly be TTL levels, rather than RS-232 levels?
On a Commodore 64, sure - but this machine was made in 1996. The
advertisements suggested that there was an upcoming communications
package that would connect to the 'net, which would (at the time) have
required a typical external modem at the other end of the serial port.
