If by "breadboard" you mean something with pre-drilled holes at .1 inch
spacing, the answer is "probably not".  I once accidentally made a PC board
with .1 inch holes for a DB-9 connector.  I got it thru the holes with a
little persuasion.  However, a 25 pin connector is a lot wider and the error
is cumulative, so it would probably require some mangling.

If this is for RS-232, you are probably only using 3 or 5 of the pins.  If
no hardware handshaking is used, then you are only using pins 2, 3, and 7.
If this is the case, you can clip off the unused pins and the remaining ones
should go into the holes without too much trouble.
