What exactly is the lowest possible baud rate?

It should be about 244bps.

Thanks

I read somewhere that you can somehow slow this down even further.

Any ideas?

I think that to go slower, you have to use the clock prescaler to slow down the entire CPU.
Or you an use a softwareSerial approach.  How slow do you want to go (and why?)
(every once is a while I slow down a serial connection to some command-line host to 110bps, just to remind myself what  it was like...  :-) )

But do you have an ASR-33?

I want to get it down to 50 baud? Using it for rtty.

Any code?
