Of course, the LEGO tools work on both machines. I suspect that the
LEGO guys are opening the private filename returned by the API
for the tower instead of the special "\\.\LEGOTOWER1" filename.

I've uninstalled and re-installed the tower drivers on the Win98 machine
just in case, and it still doesn't work :-(

I'll keep digging.

Did you escape the backslashes in the C string?

  CreateFile("\\\\.\\LEGOTOWER1", GENERIC_READ | GENERIC_WRITE,
     0, 0, OPEN_EXISTING, 0, 0);

Just a thought... it's easy to forget sometimes.

(...) 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)
