 Use OpenDevice() (instead of Open("SER:",...) and Preferences if that
indeed is what you are doing) and DoIO() with the command SDCMD_SETPARAMS
and io_Baud set to any rate needed.   Maximum is an incredible 292000
according to the dox.  Of course, don't expect the Amiga to handle a
continuous stream of characters at this rate, but the capability of
"character at a time" is there.

       I think you wanted "?" and not "."

Unfortunately, forget it.  Minimum the hardware can handle is 112.  The
device will accept down to 110, but will be bumped up to 112.
