The details of streaming information
* The serial stream always starts with an upper case "S",
the data string consists of:
S<decimal_move_frame>, <axis1_position>,<axis2_position>,........….....<axis8_position>
For Serial box v2, it was for up to 8 axes. Ch1~6 are encoders streaming, Ch9 and Ch10 are lens data.
For Serial box v3, it was for up to 10 axes. Ch1~8 are encoders streaming, Ch9 and Ch10 are lens data.
* The frame number has two decimal places, axis positions are signed integers.
1 count = 1 encoder line.
All lines are terminated with hex character 0x0d, followed by hex character 0.
* The move frame is specified as a decimal.
Where n = a number.
n.5 = 180 degrees, the position of the axes halfway through the exposure.
n.0 = shutter closed.
