I'm using Bitsy Plus CE 3.0, eVC++ 3.0 in vanilla configuration: primary connection through ActiveSync on COM1 + Ethernet tcp/ip.
When running my app under eVC debugger, I see debug output strings sent to COM2 and COM3. I write debug output via MS TRACE() macro which calls ::AfxTrace(). (I also see debug outpur in the "Debug" pane of eVC framework.)
Anatoly and I discussed this further. It appears that the COM2 observation might have been an error, as we couldn't reproduce it. COM3 debug output is normal.
If anyone else sees suspicious behavior like this, let us know. We're always on the lookout for issues that might have slipped past us!
