I'm hacking on a board that has an RS232 interface (via a Max232 chip). My new computer doesn't have a serial port, which leaves me using USB. I actually have a Serial to USB cord already, but it doesn't appear to work on any modern OS that I run (Windows 7, Linux). I'm not 100% positive, but I think it's this one:
I still have the driver CD too, which worked fine in XP, but Win7 wants nothing to do with it.
So, can anyone recommend a serial to USB cord/converter that they know works?
