Hello, at least for parallel ports, ppi might help you. There is a short example in the ppi(4) man page: To present the value 0x5a to the data port, drive STROBE low and then high again, the following code fragment can be used: int fd; u_int8_t val; val = 0x5a; ioctl(fd, PPISDATA, &val); ioctl(fd, PPIGCTRL, &val); val |= STROBE; ioctl(fd, PPISCTRL, &val); val &= ~STROBE; ioctl(fd, PPISCTRL, &val); HTH, -- Andreas Kohn <[EMAIL PROTECTED]>
