ieee1284_ecp_fwd_to_rev, ieee1284_ecp_rev_to_fwd – ECP direction switching Synopsis int ieee1284_ecp_fwd_to_rev(struct parport *port); int ieee1284_ecp_rev_to_fwd(struct parport *port);DescriptionThese functions are used to switch directions when in ECP mode. On negotiation to ECP mode the direction is forward (in other words, host-to-peripheral). Use ieee1284_ecp_fwd_to_rev to switch from forward to reverse, and ieee1284_ecp_rev_to_fwd to switch from reverse to forward. They act on…
