Wireless cables replacement technology?

I'm looking for a solution for wireless cable replacement. Basically I
would like to have some wireless technology that replaces cables from
point A to point b-z. I'm thinking about more than one RS232 cable and
I'll need to figure out the control mechanism for the control
pins. Anyone have any ideas? I'd be willing to build it myself so any
solutions would be of interest to me.

Thanks
