The Maestro wikeyer is NOT accessible to software programs at this time from both a hardware or virtual port standpoint. There is a standing request to have this feature added. Secondly there ARE well documented timing issues in the current production release of SSDR/CAT wikey emulator. They are currently being worked on. I have a hardware winkeyer in use as well while this stuff is fixed.
Hang in there gang.. the team is well aware and working on fixing these issues. Even Gerald has chimed in stating this stuff is getting fixed..
