I guess what I'm asking is if there is any benefit over IR. I've used both, only ever had a problem with RS232, though it could have been an HDBT problem.

Truth is I'm 90% done with a rack and I'm wondering if I should wire RS232 to my HDBT extenders. Also, sometimes the Ex link 3.5mm are in a bad spot. If there was no benefit I'd just use IR.

This is an Elan system, no Samsung drivers for it, though I could do one way telnet if that's all the IP was, but I have no information on that.
