Add support for serial port?

[synfinatic]

Seems like Stellarium and others? don't support connecting to telescopes over TCP/IP, but do over serial devices. If AlpacaScope presented itself as a serial device then they could talk to a remote telescope over Alpaca.

At least one person would like that: https://www.cloudynights.com/topic/797780-stellarium-macos-to-ascomalpaca/

Alternatively, listen on TCP and implement the Stellarium remote protocol? http://svn.code.sf.net/p/stellarium/code/trunk/telescope_server/
