Can someone direct me to some instruction how to set-up XL to issue RS-232 commands?

Under F2, Events, RS232. Make sure to add colons between com port settings as shown in the example, select string or bytes format. Create and label individual RS232 events then create and label your buttons, next add the events to the appropriate buttons. When your creating the Rs232 events, use the test button to see if the event you created communicates with your device.
