Tom,

There isn't a way to do this, short of patching a location in RAM to prevent the CoCo 3 from going into hi-speed mode (which effectively causes it to go from 57.6 to 115.2).  I don't have the exact location, but searching for FFD9 around the $CXXX area should pinpoint it.  Changing the $D9 to $D8 will cause the CoCo 3 to remain in regular speed and thus communicate at 57.6K.
