Use of the ppi interface

[Daniel Hilevich]

Hi, I'm using the parallel port to control some sort of a hardware (i2c). For that I generate pulses using the ppi device (geek port). The problem is that in some cases, the pulse isn't generated. What I do is sending an ioctl to make the device high (1) and another ioctl to set the device low (0). It seems that in some cases, the two commands arrive together to the device so the pulse isn't wide enough. Does the ppbus layer stores the ioctl's in some sort of a buffer and than flushes its content to the hardware? If so, is there a way to control it? The pulses should be in fixed size, so any other idea will be welcomed.
