Coherent Sapphire laser power not set at startup.

On DeepSIM the first time you access the 561 you get

Exception in thread _updater:

Which is I think a consequence of the power not being set at startup even if the laser in enabled.

I have the same error

For those who don't know DeepSIM, its 561 line is a Coherent Sapphire laser.

I don't think that's what's happening. I just tried it directly and works:

>> s = SapphireLaser('COM2')
>> s.initialize()
>> s.power
0.0

In my case it is with the 488 deepstar. I will check tomorrow if it is exactly the same error.

Must be a different one. The bottom of the error message refers to the command b'?p which the sapphire command to query the power. The deepstar laser has no such command.
