They are the xstream x24-009nsc and I looked everywhere for a baud setup but it doesn't show anything.

It looks from the literature that you just give it data and presto. ?

I know it takes 1200 baud and a broad range of data rates.

I tried taking CTS low and nothing but I don't think you need to do anything except give it +5v, ground and the serial data....it's xcvr so it has data in and data out pins.

Have a nice stubby Linx antenna on both....they're very well made modules....but they AIN'T WORKIN' as goober would say.
