I was hoping someone might have an easy adapter solution for my current = issue. This is for a project I need 5+ years ago. I have a pic that communicates to a Tripp-lite UPS using RS232. Well = Tripp-lite has gone and changed their UPS's to USB. What are my options = to support this USB plug? Code and hardware modifications? USB to DB9 = cable adapter? Other? Cost is not so much a factor as time. Thanks for any help. Take care -Jim -- http://www.piclist.com#nomail Going offline?
