(...) Claude, I've written a little C program that tries to open "\\.\LEGOTOWER1" and on otherwise identical computers (except one is running Win98SE and the othre runs Win2K) only the Win2K machine can open the file. Of course, the LEGO tools work (...) (20 years ago, 5-Feb-04, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) Ralph, I retried it with a Delphi-program that I wrote some time ago. This opens "\\.\LEGOTOWER1" without any problem: ... const DEFAULT_PORT_NAME = '\\.\LEGOTOWER1'; ... function USB_Open():Longint;stdcall; var hFh:Longint; begin (...)

(...) Yes, I escaped the characters. The identical code works on the Win2K machine and does not work on the win98SE machine with identical LEGO drivers installed. Hmmmm Ralph (20 years ago, 5-Feb-04, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) One other thing you could try is to physically disconnect and then reconnect the USB tower from the system. I've found that (on Win98 at least) the driver sometimes freezes up and won't open until after I do that little dance. Also, you could (...)
