Hi Iztok, I think you are right. (After all, you wrote the driver.)
I use the driver both in RedBoot (to connecto to GDB and download the 
software), and in the eCos itself. It is when eCos tries to run ioctl that 
it completely hangs.
It is very nice that you will spend some time fixing this. I wish I had the 
knowledge to help you.

There is no simple workaround, is there?
