This shows that the pe library has detected two P&E devices.  You can use the 
URLs it lists to select devices unabiguously.

You've given the URL 'pe:', therefore the first reported p&e device that matches 
will be selected.  As you can see from the above -i output, that will be the 
cyclonepromaxserial.  Use 'pe://ParallelPortCable:1' to explicitly select your 
parallel port device.

Do you have a cyclonepromaxserial connected?

Can you try with
   target remote | m68k-elf-sprite -v pe://ParallelPortCable m5235evb
That will provide more logging information.
