  Re: reply framing in firmdl3/rcx_comm.c
 
--- From: Kekoa Proudfoot [via Pat LaVarre] ... About message framing, I would not say that the designers at Lego had something specific in mind for RCX-to-PC messages. Framing for those messages is very ad-hoc. One thing which is very useful is the (...) (22 years ago, 7-Feb-03, to lugnet.robotics.rcx)

  Re: usb to ris 1.x rcx ir how
 
Lego's IR protocol is proprietary, similar to that used by remote controls. This means that USB/IrDA bridges will not work, nor will the IrDA ports of laptop computers. If you have a universal remote which connects to your computer, you might be (...) (22 years ago, 5-Feb-03, to lugnet.robotics.rcx)

(...) Yes or no, sorry, depending on what we mean by "a USB IR tower". If I may try again, I mean to ask: What should I buy in place of the USB IR tower of an entirely new RIS 2.0 kit?

  Re: usb to ris 1.x rcx ir how
 
(...) Do you mean use an RCX 1.0 with a USB IR tower? Nothing special required. The IR protocol is the same. The PC software, however, must support USB, and I don't think the RIS 1.0 software does. (22 years ago, 4-Feb-03, to lugnet.robotics.rcx)

  usb to ris 1.x rcx ir how
 
How do I connect USB to the IR of a 1.x RIS RCX? What hardware should I buy, from whom? Currently I'm reaching the RCX via IR via serial from a PC. But I'd rather be using the USB only, no serial, of some "legacy-free" Apple Mac's bought between (...) (22 years ago, 3-Feb-03, to lugnet.robotics.rcx)
