I'm currently using drvSerial in my device support routine to talk to a serial port. Because of hardware limitations I need to change the speed of the port. drvSerial provides a routine (drvSerialGetFile) that returns the file pointer (FILE *) for ioctl manipulation. The problem is that ioctl expects file descriptor (int). Does anyone know how to get the file descriptor from the file pointer? Thank you, Pedro.
