How to Write A (.wav) audio file to serial port using visa

Сообщение djac91 »

Hello Everyone.

i need your help.i'm doing a project in which i have to make a phone
call through a modem and play a .wav file over the phone when the
remote party picks up.
i have made a vi. Here i have used the modem within my laptop (modem
used for dial up connections).my modem is Agere systems HDA modem.
it responds to 'AT commands'. When i execute the vi ,i get a call to
the number after sometime.when i pick up the phone ,after few seconds
the , the .wav file is played back through the phone. but it doesn't
play the entire .wav file.i hear only few seconds of audio, after that
the call gets diconnected.

i think the way i write the.wav file to the port is wrong.also i have
doubt's about buffer size required,baud rate etc.

i have attached the vi along with audio file.please execute and
check.choose the path for audio file before execution.choose the files
according to your labview version.choose the com port for your modem
and also change the code accordingly.please correct the code .

PLEASE READ THE ATTCHED PDF FILE BEFORE CHECKING THE VI. I HAVE GIVEN
DETAILED DESCRIPTION OF THE VI IN THAT
