I am considering doing a LEGO competition for next semester in which the robots have to find and extinguish a flame (candle, for ex.) Like the Trinity College contest, I guess.

Cut the battery wires and add a polarized two wire connector. Then you are able to substitute any desired (...) (25 years ago, 22-Nov-99, to lugnet.robotics.handyboard)

Kalyan, During the two weeks that you didn't use your HB did you install any software that uses _any_ serial port? When I installed Windows CE Services it interfered with serial I/O. To talk to other serial devices on com1 it's necessary to disable (...) (25 years ago, 22-Nov-99, to lugnet.robotics.handyboard)

it sounds like it's a problem with your downloader configurations -- neither of them can open the COM port. were you able to connect "Direct to COM1" with HyperTerminal when doing the Windows Serial Debug? it's odd that that would work and then the (...)

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)
