.br
The optimal values depend on the buffer behavior of the drive.
.br
There are also timing parameters "timeout_sec=", "min_usec=", "max_usec=".
Read the description of burn_drive_set_buffer_waiting() in libburn.h,
before setting them to non\-default values.
Parameter "timeout_sec=" defines after which time of unsuccessful waiting
the modesty shall be disabled because it does not work.
.br
Parameter "min_usec=" defines the initial sleeping period in microseconds.
If the drive buffer appears to be too full for sending more data, the
program will wait the given time and inquire the buffer fill state again.
If repeated inquiry shows not enough free space, the sleep time will
slowly be increased to what parameter "max_usec=" defines.
.br
Parameters, which are not mentioned with a \-modesty_on_drive command,
stay unchanged.
Default is:
.br
\-modesty_on_drive off:min_percent=65:max_percent=95
\-modesty_on_drive off:min_percent=90:max_percent=95:timeout_sec=120:min_usec=5000:max_usec=25000
