Feast your eyes and marvel at the modern stupidity i was faced off with today, a new (2024) CNC plasma cutting machine using RS232 or plain old serial at 19200 baud to communicate with the PC, running windows 11 while machine controller running in 32 bit mode!!!
Hypertherm PowerMAX 65 attached to the same box as the PC, with the same DB9 connectors that were inadvertently plugged into the wrong places. Plain simple stepper drives and motors, THC with Ohmic probing, toroidal transformer, etc, or the usual.
RS232 is very flaky at the best of times, but today besides the win s#it, it worked after setting the baud rate and stop bit and flow control.
Considering myself lucky!

You restrained yourself from converting it to Plasmac while they weren't looking, then?
