Man, all those caps sure makes it hard to read. I noticed your in the subject line and tried singing it, but nothing rhymes...

I think you're forgetting that the on-board port (Port 1) on the Micrologix can be used for purposes other than programming. The LRP gives you an ADDITIONAL serial port. Therefore you have 2. You can connect the HMI to port 1, and the modem to port 2.
