David,

Here's a long winded answer:

The version of Device::SerialPort that we include with mh doesn't support
non-standard serial ports.  However, the latest version in CPAN does, but
based on the comments in the source, it is only supported on OSX.
Device::SerialPort is based on POSIX interfaces but is looks like OSX has a
non-standard POSIX extension to allow custom rates.  It might work in Linux,
but I doubt it.

I suggest instead that you use setserial outside of mh.  "man setserial"
will show you how to set custom baud rates and divisors.  You may need to
patch mh to allow a "don't touch the baud rate on this serial port" setting.
