I playing with the serial.c. The serial driver handles interrupts from the serial hardware. If the driver is put to sleep via the interruptible_sleep_on command to wait for the CTS to go high, how does it handle the interrupts. (as it is already been put to sleep). I thought of using fork to keep the parent waiting till the child wakes up or rather exits after an interrupt e.g when CTS goes high but fork does not work in kernel space. Can any one help!This email and any files attached are intended for the addressee and may contain information of a confidential nature.
