Ringer volume and vibrate mode

[ikaplan]

Hello,Could someone please tell me if it is possible in basic4ppc to change the phone ringer volume. Also, is this some way to switch between ring and vibrate modes programaticly? I have searched tghrough existing libraries and also through forums. I found just the volume control for playing sound and was not able to find any for ringer volume. Not sure, if it is even pocible.
Many thanks in advance!
