ieee1284_ecp_fwd_to_rev, ieee1284_ecp_rev_to_fwd - ECP direction switching
int ieee1284_ecp_fwd_to_rev(struct parport *port);
int ieee1284_ecp_rev_to_fwd(struct parport *port);
These 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 the parallel port associated with port, which must be claimed.
