Looks like the biggest problem with controlling the OI inputs over RS232 from a laptop is that there is only 1 data pin on the serial protocol. I could spend some extra time writing a simulator for the OI and just use an adapter to run the radio straight from my laptop, but that seems like an excessive amount of work. If anybody knows of a simple way to send different values to the different pins on each port of the OI, let me know. I'd still like to do this (even if slightly impractical) because of the flexibility it will allow me. If I'm able to get it working, I'll write a whitepaper and help anybody get the same system up. Appreciate the help.
