In SX Microcontrollers, SX/B Compiler and SX-Key Tool, warnerworking wrote: I also hade intermittent problems with the XS Key and the serial port, Like you I could find a basic stamp board I designed and have been using for years, but not the SX although in my case I was using a USB with a serial adaptor, sometimes the SX Key would find it and sometimes not, I could get it to work by uninstalling and reinstalling the drivers but it was glitchey, I suspect that part of the problem might lie in the way the SX Key program determines what ports are available to the operating system. I finely hade to install two new serial ports on my PC and haven't hade any serial port problems since. However I never did get the Debug to work so I know what it feels like to have something you paid for not work as well as we have come to expect from the other Parallax products. Good Luck. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=188854#m189414 Need assistance?
