I just bought myself a new Handspring.  My first problem is that it came
with a USB cradle and I want a serial.  New cradles cost $30.  I figure
there can't be too much difference between the two cradles.  Is there any
sort of simple hack to make my USB cradle a serial?  I want a serial for
several reasons, most notably to use it as a VT220 terminal.
