Hallo Ross!
This is just the problem, I can not download programs or the legos.srec.
Both, firmdl3 and dll give the message "bad ir link".
I have an other linux computer on which (with a built in com port) dll
and firmdl3 work correctly.
I compared the setserial output for ttyS0 on both computers. Setserial
on the notebook pcmcia card recognized a UART 16950/954, setserial on
the other computer a 16550A. This was the only difference.
I could not find any error messages or warnings relating to ttyS0.
Regards.
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.
