SDNC RS232 Communications software by Surfcam
SDNC RS232 communications software by Surfcam use to be offered for free on there website. Unfortunitly that is not the case anymore. This was one of my favorite free RS232 Programs that I still use today as I still have a copy. However its only available to you if you own a seat of Surfcam. I think this was a great way to promote there software, so if you would like to make the request to them for the free version again it might be worth a try.
This software can have multiople machines all set up with different settings. The layout and self explanitory menus are great for anyone to use.
