Z80 SIO or DART?

Z80 SIO or DART? - 03/10/19 10:58 AM

Just checking: should I use Z80SIO (in z80sio.cpp) or Z80SIOn (in z80dart.cpp) for a new device?
I have the impression the latter is being phased out and should not be used for new developments. Right?

z80sio.cpp is preferred (it's a newer implementation) but if it comes up lacking features you need, use the other one.

I think the one in z80sio.cpp has more functionality at this point. You you just need asynchronous modes, or do you need synchronous modes as well? SDLC mode mostly works, apart from some corner cases, but BiSync is still flaky.

Just good old asynchronous I/O.
