ELSA MicroLink with voice library

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hello,

I'm using an ELSA Microlink 56k and the 'mgetty-1.1.14'
package.
Linux Kernel 2.0.33
When starting some of the voice-library-scripts, for example
'demo.sh' I get an error in /var/log/vm.log

-------------------------------------------------------------------------

To find the problem I wrote a simple script

-------------------------------------------------------------------------

#! /usr/bin/vm shell

function receive
     {
     read -r INPUT <&$VOICE_INPUT;
     echo "$INPUT";
     }

function send
     {
     echo $1 >&$VOICE_OUTPUT;
     kill -PIPE $VOICE_PID
     }

ANSWER=`receive`
echo "HELLO SHELL=$ANSWER"

send "HELLO VOICE PROGRAM"
ANSWER=`receive`
echo "READY=$ANSWER"


send "DEVICE INTERNAL_SPEAKER"
ANSWER=`receive`
echo "READY=$ANSWER"


send "PLAY /var/spool/voice/messages/ansage.rmd"
ANSWER=`receive`
echo "PLAYING=$ANSWER"
------------------------------------------------------------------------

The file 'ansage.rmd' is being played, but there is still an
other error message in 'vm.log'

Where is the mistake? Who can help!

Thank you very much!
