Is it somehow possible to both be sending and recieving from /dev/i4btel0?
I would like to send voice to the caller, while also recieving data,
eventually decoding with dtmfdecode to make a voice-response system.
dd of=${DEVICE} if=${LIBDIR}/leifans.al bs=2k >/tmp/out.log 2>&1 &
sleep 2
dd if=${DEVICE} of=/tmp/answers.al bs=2k count=100 >/tmp/in.log 2>&1
Without "sleep" the last dd reports "device busy"
With "sleep" the first dd reports "device busy"
Would it be possible for a single program to open the device for reading
and writing simultaneously?
Wish mode on:
A program, which sends an audiofile to the device, while listening for
DFTM tones. Exit, when X tones are decoded, or a member of string S, or Y
seconds after the audiofile is finished.
usage:
string=`playndecode enteryourcode.au -n4 -e#* -t30`
Play the file, wait for 4 digits, or exit on #/*, timeout 30 seconds.
Leif
