[PHP] problem with sending AT command in php

[a dehqan]

In The Name Of Allah The compassionate merciful

Hello ;
Am trying to send AT commands to my GSMmodem device , in linux with PHP
Am sure it is /dev/ttyusb1
But with [URL="http://pastebin.com/aut4ygXf"]this code[/URL] device respond
the same command and code prints that command
e.g if we send ATD00 it responds ATD00 , or with AT it responds AT instead
of Ok, why ?

Regards dehqan

dio_write($handle, 'AT') & dio_write($handle, "AT") make firefox times out
on Waiting for localhost ... .
But dio_write($handle, "AT\n") makes it prints AT exactly the same command
or  A > A , ..

\n is for Linux
\r is for Windows

Thank you all for attentions ;
Weird but solved with using another symbolink of Device
Weird because other App in linux in the same time were using for example
/dev/ttyusb1 but php code works with /dev/ttyusb3 ..
