Mark, The answer to both is YES. Remove the four screws from the corners of the HB and remove the board and batteries from the plastic box.

go to start->settings->control panel->ports and see if COM1 is available, if not then use the the com port that is listed there, if there is nothing there then there is something wrong. Also make sure any background apps aren't using the com port. (...) (25 years ago, 21-Nov-99, to lugnet.robotics.handyboard)
