problem sending audio with modem

[Buzzchewan]

Hello,

I am trying exactly what you said about to send a voice message by the modem...

But when i do the AT+VTX CONNECT, i am playing the message by a shell script : cat sirene.wav > /dev/ttyS0 ...

But i dont know how, (or if its good) to send a <DLE><ETX> to stop the modem...Well im french sorry for my bad expression

Better to show you what i did, and if you can see what is wrong...Would be nice :

In a chat script
