Hi Michael,
Try the --slow option on firmdl3. This forces it to use the slow download
speed, and may help. Also, use --debug to display more debugging info. This may
help someone here to work out what the problem is.
I'm not sure what the equivalent options are in dll (or even if they exist!)

| Hallo Ross! I found in the linux pcmcia forum, that the socket pcmcia card, which I am using, sets the speed internally four times faster then expected. Is there a possibility in the firmdl3 and dll-source to divide the speed for the serial port by (...) (23 years ago, 23-Aug-01, to lugnet.robotics.rcx.legos)
