I'm working with a marking machine that has a Spectra Physics
T20-BL10-106Q laser and a Scanlab RTC4 controlling a Scanlab scanhead.
Everything is working pretty well, though I still have lots to learn.
One thing I'd like to do that I haven't figured out yet is to issue a
command to the laser over the PC's serial port at the beginning and end
of each marking job. Specifically, I want to send the command to put
the laser in run mode at the beginning and standby mode at the end. Is
there any way to do this?
