Is there any remark, why the programmer decided to use (255 - 64) instead of 191 ?
That's because minor numbers for ttyS* are starting from 64.

Hi,
The helper function ser_to_dev does not need to be in global scope, so
make it static.
"warning: symbol 'ser_to_dev' was not declared. Should it be static?"
Thanks very much!
