| Hey Christos,
| about fix in function comshutdown () I stand by my suggestion.
| I believe that changing the flag IER_ERXRDY to IER_ERLS we will obtain
| the following two benefits
| 1) there will be no more interruptions generated for this COM after the
| shutdown. That would seem to be the intent of this part of the code.
| 2) Allow the user to enter the debugger even after the shutdown, sending
| a BREAK on the serial port.
| I also believe that it wasn't such a wise idea to mix the com_shutdown
| subject in the same PR problem with kgdb.
| Wouldn't it be better if I open another PR to deal with this matter?
Sure, I agree with the current changes. If you want, please open another
PR to fix the shutdown issue in a better way.
