Add direct support for serial devices

If possible, support serial device connect will be better

Current via Basic Profile, use screen or minicom command connect to device serial device.

Thank you for the suggestion, serial com support is in our wishlist, but with lower priority. It requires dedicated heavy work, we have to think carefully before set to work on it.

@yang This would be a very great feature. We use serial connections regularly at work and I would be willig to pay a few extra bucks for my whole team (15 users) for this feature.
