ieee1284_set_timeout - modify inactivity timeout
struct timeval *ieee1284_set_timeout(struct parport *port,
struct timeval *timeout);
This function sets a new value for the inactivity timeout (used for
block transfer functions), and returns the old value.
The port must be claimed.
The timeout parameter may be NULL, in which case the old value is left
This function returns a pointer to a struct timeval representing the
old value. This uses the same storage as the port structure, and so is
not valid after closing the port.
Note that this is an inactivity time-out, not an absolute time-out.
During a data transfer, if the peripheral is inactive for the length of
time specified then the host gives up.
It is also advisory; no guarantee is made that the transfer will ever
