errata

In the function 'get_switching_step()', the documentation of the relevant command (Get Step 205_1 on p54) states that the returned array is 6 bytes long in the format
- [0] = '205'
- [1] = step_index
- [2] = swtich_state
- [3] = dwell_0
- [4] = dwell_1
- [5] = dwell_units
This arrangement is incorrect, at least for firmware version 'A3' which is all I have access to. The actual returned array is as follows:
- [0] = '205'
- [2] = switch_state
- [3] = dwell_0
- [4] = dwell_1
- [5] = dwell_units
This means that from the returned array alone the relevant step cannot be determined
