Specifically, changes to the z80sio has caused this, but where other failing sets were resolved rather quickly (ccs300, jgz80, uts20), this one fell through the cracks and was not reported here when the next release happened.

This was really my mistake for not having originally understood how MAME's RS232 emulation worked. I thought that inversions were necessary since the 1488/1489 line drivers and receivers are technically inverters, but MAME uses the logical levels rather than the signal levels.
