"procomm will download and log very nicely"

Note that Procomm is a terminal emulator; it was designed to work as a terminal attached to a "Host" computer.
Therefore, when Procomm (especially earlier versions [1]) talks about "download" it means "download from the Host;" similarly "upload" means "upload to the Host"

You are effectively using Procomm as the "Host" for your target board - so the roles are reversed; therefore, when you want to "download" your code to your target, you need to choose Procomm's upload option!

[1] Actually, on my version (ProComm Plus 32, v4.7) , they use the terms "send" and "receive" - which is less ambiguous!
