    NAME

    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);

     

    DESCRIPTION

    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.

     

    RETURN VALUE

    E1284_OK
    Direction switched successfully.

    E1284_NOTIMPL
    The port lacks the required capability. This could be due to a limitation of this version of libieee1284, or a hardware limitation.

    E1284_INVALIDPORT
    The port parameter is invalid (for instance, perhaps the port is not claimed).
