Implement a --hang or --wait function for %serialconnect #39
Description
I'm having problems with boards that sleep, or have code in them that intentionally disables their serial functionality. The scenario is:
I plug the board in
It runs through its code
I have a window (1-3 seconds) in which I need to run %serialconnect, which I often miss
If %serial connect had a --hang or --wait feature that constantly polled for serial devices that are present on the system, this would make my life a lot easier.
