You can use WinSPM to connect to any version of Legend. I went back to using version 6, because version 7 seems to have some bugs. When you get the error "failed to connect" and it says check the cable, just try reconnecting again. More often than not, on the third attempt, you will connect just fine. I don't why it does this, and neither does Avaya. WinSPM 6 seems to be a lot more stable.
