Transfer files to/from N* CPM image?

I have three different commercial implentations for the Horizon .. a couple of different versions of the offical NorthStar CP/M release, LifeBoat CP/M for the Horizon and one called Xitan. I tested all of them this afternoon, and none of them appear to have a hardware device mapped to read the secondary serial port -- some of them have devices mapped to write to it, and some of config/gen programs allow you to select you printer to be on either the parallel or secondary serial port... Oddly, I did find code to read it - right next to the code that writes it, but none of the devices activate that code (I set a breakpoint in it and tried "everything"). Thats great when you are working with a physical system, however I often find it easier to work under the simulator (single PC)... especially when the hardware has been stored away as most of my collection is - the newly added "mount reader file" feature I mentioned in my last post will let you do the PIP thing by stuffing a file in via the console interface. I wonder if any of the multi-tasking OS's capable of running DOS software support virtual com port connections between sessions ... this would let you run the simulator and a terminal emulator capable of xmodem etc. transfers on the same PC.
