PARPORT_NEGOTIATE(9)                  Parallel Port Devices                  PARPORT_NEGOTIATE(9)



NAME
       parport_negotiate - negotiate an IEEE 1284 mode

SYNOPSIS
       int parport_negotiate(struct parport * port, int mode);

ARGUMENTS
       port
           port to use

       mode
           mode to negotiate to

DESCRIPTION
       Use this to negotiate to a particular IEEE 1284 transfer mode. The mode parameter should
       be one of the constants in parport.h starting IEEE1284_MODE_xxx.

       The return value is 0 if the peripheral has accepted the negotiation to the mode
       specified, -1 if the peripheral is not IEEE 1284 compliant (or not present), or 1 if the
       peripheral has rejected the negotiation.
