No, I don't have it working yet.

Hi all, I think we have finally gotten a cross compiler built for Solaris. I am still not 100% sure. I will not say that we have until I have seen a robot driving around the table which has a program written in legOS and downloaded in it. However at (...)

(...) Do you mean gcc 2.95.x ? If so, yes, i did it 2 days ago. The native compiler on my linux box (kernel 2.2.13, glibc 2.0 ) is a self compiled gcc 2.95.1.

Hi Erik, Starting after the 1.0.7 version, echo from RCX was disabled (controlled by RCX_ECHO variable, off by default). Current version (1.1.0 as I remember) shouldn't show any echo. At least with "standard" terminals. I've tried Hyperterminal, (...) (25 years ago, 18-Nov-99, to lugnet.robotics.rcx.pbforth)

Well, it's hard to say what the problem might be. Since you've got the green LED going, you've probably got the cable wired correctly. And yes, it's 2400 baud, 1 start, 1 stop, 8 data, odd parity. Perhaps the packet isn't correct. Here's a sample (...) (25 years ago, 16-Nov-99, to lugnet.robotics.rcx)
