change speaker

I have wavecom fastrack 1306b. Wavecom consists two speakers:by default use speaker ONE. How can i set speaker two is active from Open At program?
With AT cmd this like “at+speaker=1”, but need from program

You can send AT Commands from an Open-AT application: see the ‘Commands’ API in the ADL User Guide - specifically, the section ‘Run AT Commands’

Super! Thx!!!
