It didn't do 110, but I chanced across one USB/serial adapter that goes down to 75 bps.
which fortuitously was just what I needed at the time for the model 28 teletype (with the appropriate gears) I was attempting to drive.

The 75 wasn't readily accessible, I had to go to a low level in the unix config code and try sequential factors in the
configuration for the rate, 75 being another factor of 2 down in the standard rate series 19,200 . . 9600 . . 1200 . . 300 . . 150 . .
