[PHP] Escaping BASH quotes

Hi guys,

I need to send a command to BASH with quotes ... I have tried escapeshelarg()
and escapeshellcmd ... but somewhere I still have a bug:

here are the BASH commands I need to escape:
echo -e "\rMYCOMMAND\r" > /dev/ttyS1
echo -e ":AB7ASD-02:Command Msg:VF3LPO" > /dev/ttyS1
echo -e "\r\03\r" > /dev/ttyS1

At the moment I am using exec() to send these lines ...

Any pointers?

Thank you
