Communication commands
The laser is delivered in Auto-start mode (see section 3 for Auto-start sequence description). For system integration
the Auto-start sequence can be disabled and the following commands can be used to control the laser. As long as
power is supplied to the laser the temperature control elements are always operating to reach set-point values and
the laser will be idle waiting for the next command. All arguments are in lower case and separated by a space (ASCII
32).
NOTE
some commands require Auto-start to be disabled but others will work when Auto-start is active.
