Thanks , i downloaded the new version , now it does not crashes anymore.
Just one more question , if you know the answer :
When i write to device eg using (write-bytes #"dt\r" out)  and try to read
back from it (read-byte in) , most of the time nothing comes back.
Is there special setting for output and input port for serial ports.
Though everything works smoothly in linux.
