Help with Xbee API

Hi, everyone:
Could anyone, please, tell me how I can send text in API mode? I am using two XBees Series 1 as well as two Arduinos Dec.
Thank you very much.
P.S. I am using Andrew Rapp's XBee.h library.

Use the XBee_SendPacket function to send a packet where the data member is the text you want to send.
