* - disable device when error indecates that the problem is not solvable on reconnect
- introduce a preOpenDelay of 2 seconds (currently value is hardcoded)
* rs232:
- make preOpenDelay available via webui
- fix preOpenDelay
- add basic usb serial detection
* - revert 3819ae7
- fix schema files
* make json checks compat with utf8+bom
* make shutdown effect a bit more flexible
