Default device name

[wschoenell]

The default behavior of chimera is to set the device name of telescope, camera and others as /dev/ttyS0. This causes confusion when the instrument itself does not haves this property. This leads the user to think that this device is connected to the serial port.

An example is shown below. TheSkyTelescope does not uses a "real" device on the computer.

C:\Anaconda\Scripts>python chimera-tel --info
========================================
telescope: /TheSkyTelescope/paramount (/dev/ttyS0).
current position ra/dec: 02:21:51.981 -83:47:03.168
current position alt/az: +51:50:16.605 +180:56:34.501
tracking: enabled.
========================================

I suggest to change the default device to None.

As far as I remember, there is no forced config 'device', so each instrument that in fact needs a 'device' config adds it. So what's wrong with having sane defaults? You'll need to config it anyway.

If the issue is seeing '/dev/ttyS0' and thinking that it is in your machine while that port is in the remote telescope machine, the soluton is:

C:\Anaconda\Scripts>python chimera-tel --info
========================================
telescope: /TheSkyTelescope/paramount (/dev/ttyS0 @ <remote-machine-name-or-ip>).
current position ra/dec: 02:21:51.981 -83:47:03.168
current position alt/az: +51:50:16.605 +180:56:34.501
tracking: enabled.
========================================

The issue is to see /dev/ttyS0 on a device that does not even use a serial port to access it. In the example that I've sent, the device is on the local machine. It is connected to the computer by a serial port, but chimera access it via windows COM+. This confuses the user.

Also, the /dev/ttyS0 is shown on most of the USB cameras. A sane default for me would be None, or something alike.

I, for a change, agree with William :-) , I like None better than /dev/ttyS0

ok, it makes sense to leave device with sane default only where it matters. waiting for the PR.
