Need support for P-200 controller for SH-242

[devangs3]

Is there any support for the P-200 controller that comes embedded into the SH-242 chamber?

The P300 and P200 have identical communication protocols. Use the humidity P300 example and it will work correctly for serial interfaces.

The library could be modified to work with the TCP protocol available on port 57732 easily; change 10001 to 57732 on the linked lines:
