Ubuntu overlay trouble

I loaded the BB-UART2 overlay on Ubuntu 13.04 on my BBB. /dev/ttyO2 appeared as it should, but I can’t communicate with my device (an XBee radio). Anyone else experiencing something similar?

Just wanted to follow up on this. It turns out that the overlays were working correctly. Somewhere along the way the configuration files that loaded my daemon for the XBee communication got modified so this didn’t happen.
