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 4? I would try it myself, but I am not familiar
with the source and need an advice, where to change.
If that is not possible, I would try to install legos on win2000,
because the port is working fine under win2000. Do you know, if it is
possible, to use cygwin and gcc2.95 (I want to use the c++ support in
legos0.2.5) under win2000.
I'll post these questions as new threads again, perhaps somebody knows.
Regards and thanks for advice
Michael

| 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 (...) (23 years ago, 18-Aug-01, to lugnet.robotics.rcx.legos)
