Thanks again, (...) (21 years ago, 14-Aug-03, to lugnet.robotics.rcx.legos)

Somewhere on the LEGO site it says that Serial > USB is not compatable -- If you must, why not just buy a USB IR tower from PITSCO LEGODacta for $30? If you have the SDK 2.5, or even the SDK 2.0, it comes with the driver for the USB tower (in the (...) (21 years ago, 14-Aug-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

Man, this is fantastic. Since moving over to OS X about a year and a half ago, I've been ignoring my RCX (retired the tired/crash prone PC forever!! Running Linux now though) and haven't played with it for lack of a development environment for OS X. (...) (21 years ago, 13-Aug-03, to lugnet.robotics.rcx.legos)

Hi, (...) Ptr points to the length byte of the first free block (...) *(ptr-1) actually is MM_FREE and is now set to the callers id. (...)

(...) <snip> (...) I've never looked at brickOS code, but here is my take: By the time you hit line 2, you've found a free block that is big enough. Line 2 sets the owner of the block. Line 5 decides if the block is oversized enough to split. Line 6 (...) (21 years ago, 13-Aug-03, to lugnet.robotics.rcx.legos)

(...) O.K. I will try a re-install of Cygwin, although I have re-installed at least four times previously. As I say, I get a little farther each time.

(...) I am inclined to agree with Ed. I think your cygwin install is fouled up somehow. Can you check the version of the cygwin1.dll in your cygwin bin directory? I'm running 1.3.12-1 (which is a fairly old version). John Hansen (21 years ago, 11-Aug-03, to lugnet.robotics.rcx.legos)
