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

There are lots of options - ZigBee, Bluetooth, Wi-Fi, proprietary or
custom solutions are all options, they all differ on range, data rate,
power requirements, and ease of implementation (software support). I'm
still not too clear on your requirements...

What kind of devices are you connecting? Embedded/battery-powered
devices or larger ones with a little more available power?

What data rate and range do you need?

What kind of data are you trying to send? Are you only replacing RS232
connections or are there other, maybe custom, comm protocols?

Are you looking for ready-to-go modules in boxes that you just need to
hook power+RS232 into, small radio modules that require some MCU work,
or would you want to build your own radio+MCU solution?

Right now I'm just investigating, I have almost no solid requirements.
I just want to know what's available. We may buy, we could build, most
likely its async, byte oriented, most likely RS232. The speed would
probably be 4800 - 56k, probably a lot of 9600. All the device would
have AC power.
