From what I've been able to figure, you need to bypass the irDA queue on the Palm to send straight bits over the IR port. This is possible by going to the hardware itself. OmniRemote can do it, and so can we (if we figure out how!). It's been in my (...) (24 years ago, 7-Feb-01, to lugnet.robotics, lugnet.robotics.rcx.pbforth)
