Hi,

you can use sysfs entry for gpio and write to /sys/class/gpio/export, /sys/class/gpioN

If you have gsm modem driver sources you can also do pin operation there.

1 . You can do file operations from ril code.

2. For test add absolute path to kernel-header but it has sense only with ioctl and device file.

Generally linux/gpio.h is header for drivers - but I can be mistaken
