Just to make sure, you're either explicitly setting the output port to
unbuffered or using `flush-output', and it still doesn't flush?

Unfortunately, I don't know about setting COM1 parameters. Maybe you
can use the `mode' shell command via `system'? Our use the FFI to call
functions like SetupComm()?
