Welcome to Sitepoint Farhan.

You can use the fopen, fwrite etc … to write to serial ports.

Am trying to send AT commands to my GSMmodem device , in linux with PHP
Am sure it is /dev/ttyusb1
But with this code 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 ?

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 …
