help with Airborne 802.11b Wireless LAN Module

Has anyone gotten this to work?

I have wired it up and can telnet into it to give it cli commands. However I can not talk to it over rs232. I know all the port settings are correct because I can set them over telnet. When I send a command over rs232 garbage data is sent back. Does anyone have an idea on what I could be doing wrong?

thanks
