Using rcomm with procomm seems to work ok, with one execption. I typed exit at the dos prompt, to reutrn to procomm and god disconnected. I was downoloading a file with rcomm in the background. I think the idea is that if you have run procomm, and then popped up rcomm, and are downloading, don't try to get back to procomm. At least not untile the transfer is through. Overall, it seems to work just fine.
