Sending command to GSM Modem using php Settings

the php_serial class sets the com port line by line. Windows seems to not be able to get the correct settings this way. Whenever I set the data bit to 8 the parity bits goes back to even. All these have to be done in one command line. So we have to modify the php_serial class to run the command in a single line and it solves the problem, for now.. :)
