Detailed Description

SequencerCommand to perform a read operation into from a hardware device.

This Command corresponds to the read method in the HardwareDeviceInterface. The read value is put into a variable. The syntax is :

read item $varname [offset]

'offset' is an optional parameter (default is 0) and can be a constant or a variable name.
